The AppleCORE ASCII file is a text file written in a relatively simple format.

Each line, terminated by a carriage return, represents a record of some element of

data. (A few record types require two lines.) There are at present 69 record types.

The record type is indicated by a 3 character upper case alpha string at the begin-

ning of each record. The 69 alpha codes are listed below:

The following records provide information regarding the core location, date,

elevations, etc. and should only appear once. All are optional and do not need to

be in any particular order.

WNM - Well nameTWP - Well location record (Township Range System)LOC - Well location record (other system)LAT - Well location record (Lat - Long)ELV - Elevations record (KB and ground)UNT - Units record (feet or metres)DAT - Date recordLGR - Logger recordRMK - Header remarks recordTOP - Box top position recordCOL - Box columns record

The following records represent the logged data, and can appear as often as

required. All are optional and do not need to be in any particular order.

BOX - Box recordNDR - Empty box space record (previously “Not Drilled”)LTH - Lithology recordPHY - Physical structure recordACC - Lithologic accessory recordICH - Trace fossil (ichnofossil) recordFOS - Fossil recordPTP - Pore type recordHYD - Hydrocarbon indicator recordFRA - Fracture recordDIA - Diagenesis record

In addition, there are 22 record types that are used exclusively for Hard Rock

and Thin Section descriptive data. These records can appear as often as required.

However, because AppleCORE stores them in a relational hierarchy, some are con-

sidered “parent” records and others are “child” records. They are therefore required

to appear in a particular order. (See the section “Hard Rock Record Formats”.)

The formats of the ASCII files are described here in FORTRAN format nota-

tion. Each line of the ASCII file represents a new record except for text and remarks

records which consist of 2 lines. Depths may be recorded in feet or meters as se-

lected by the user when creating the ASCII file.

NOTE: An asterisk indicates a null field set up for future use but not presently

implemented. 999 or 998 is used in the data files to indicate a null field.

NOTE also that there is an option available when exporting to an ASCII file

that will write the core and box numbers for each record. If “Include Core and

Box No.s” is turned on from the export dialog, two additional fields are written

to each record. These two fields directly follow the 3 character record type mne-

monic and are in the FORTRAN format: I4, I4. They contain the core number and

box number respectively. AppleCORE will import records in either format. Note

also that BOX and NDR records always have core and box fields in their records.

Following are each of the record formats in FORTRAN notation followed by

an explanation of each field:

Well Name Record: (A3, 1X, followed by variable length character string endingin carriage return; maximum string length: 255 characters)A3 ‘WNM’

There are 15 record types used to describe Hard Rock data:

HRK - Hard Rock Lithology RecordMIN - Mineral RecordGRM - Groundmass Mineral RecordALM - Alteration Mineral RecordVOI - Voids RecordHRT - Hard Rock Texture RecordALT - Alteration RecordOGM - Overgrowth Mineral RecordIGM - Intergrowth Mineral RecordICM - Inclusion Mineral RecordVFM - Void Filling Mineral RecordCRM - Corona Mineral RecordCIM - Corona Intergrowth Mineral RecordRRM - Reaction Rim Mineral RecordRIM - Reaction Rim Intergrowth Mineral Record

The Hard Rock Lithology Record is the top level record or “parent record”. All

of the other records are optional “child records” and must be associated with a

parent record. The child records need not be in any order except that all child records

must follow the parent record.

Each Hard Rock Lithology Record can have only one Voids Record, Alteration

Record, and Hard Rock Texture Record. But it can have multiple Mineral Records,

Groundmass Mineral Records, and Alteration Mineral Records. All of these child

records may have optional child records of their own. The number of associated

child records of each type is always indicated in a field of the parent record.

Following is AppleCORE’s write order for the ASCII file, indented to show the

parent/child hierarchy of records.

Many records include a remarks text field. There are two types of text fields: a

“Long Text Item” and a “Short Text Item”.

- A Long Text Item can be any length (but 32K characters max) and can contain

any character including carriage returns. A field in the record gives the number of

characters in the Long Text Item and then the text follows on the next line (i.e. af-

ter a carriage return). The text ends in a carriage return which is not included in

the character count.

- A Short Text Item can have a maximum length of 255 characters and cannot

contain carriage returns (AppleCORE will prevent carriage return input). In the

ASCII file, a carriage return delimits the end of the Short Text. The carriage return

character is the Macintosh carriage return (ASCII Hex 0D)

If the user can make multiple selections from a set of choices, then the field is

an array of Booleans (16 or 32) , represented by 1’s and 0’s. See the Hard Rock Code

Key for more information.

to the top level HRK record. These two fields directly follow the 3 character record

type mnemonic and are in the FORTRAN format: I4, I4. They contain the Core

number and Box number respectively. AppleCORE will import records in either

format. None of the child records will contain the extra Core and Box fields.

Mineral Record

Groundmass Mineral Record

Alteration Mineral Record

These three records are used to describe the major rock-forming mineral in a

The Thin Section ASCII Record Format uses an hierarchy of the following 17

record types:

THS - Thin Section RecordTMN - Thin Section Mineral RecordTGM - Thin Section Groundmass Mineral RecordTAM - Thin Section Alteration Mineral RecordVOI - Voids RecordTST - Thin Section Texture RecordALT - Alteration RecordOGM - Overgrowth Mineral RecordIGM - Intergrowth Mineral RecordICM - Inclusion Mineral RecordVFM - Void Filling Mineral RecordCRM - Corona Mineral RecordCIM - Corona Intergrowth Mineral RecordRRM - Reaction Rim Mineral RecordRIM - Reaction Rim Intergrowth Mineral RecordRBM - Ribbon Grain Mineral RecordCOM - Crystal Preferred Orientation Mineral Record

Many of these records are also used in the Hard Rock Lithology Record. Only

the additional records unique to thin sections are described here (THS, TMN, TGM,

TST, TAM, RBM, COM). See the Hard Rock Record Format Description for infor-

mation on the others.

The top level Thin Section Record is similar to the top level Hard Rock Lithol-

ogy Record except that it contains no “contact” field. There is also a field for a sample

ID, and for the name of the individual who described the thin section.

The Thin Section Mineral Records (TMN, TGM and TAM) are similar to the

Hard Rock Mineral Record (MIN), except that there are some additional fields to

describe optical features.

The Thin Section Texture Record (TST) is similar to the Hard Rock Texture

Record, except that inappropriate references to Sulfides have been removed. There

are also several additional fields to describe microscopic structures.

Thin Section Record Formats - Introduction

27

The Thin Section Record is the top level record or “parent record”. All of the

other records are optional “child records” and must be associated with a parent

record. The child records need not be in any order except that all child records must

follow the parent record.

Each Thin Section Record can have only one Voids Record, Alteration Record

and Thin Section Texture Record. But it can have multiple Thin Section Mineral

Records, Thin Section Groundmass Mineral Records, and Thin Section Alteration

Mineral Records. All of these child records may have optional child records of their

own. The number of associated child records of each type is always indicated in a

field of the parent record.

There are two types of text items: a “Long Text Item” and a “Short Text Item”.

A Long Text Item can be any length (but 32K characters max) and can contain any

character including carriage returns. A field in the record gives the number of

to the top level THS record. These two fields directly follow the 3 character record

type mnemonic and are in the FORTRAN format: I4, I4. They contain the Core

number and Box number respectively. AppleCORE will import records in either

format. None of the child records will contain the extra Core and Box fields.

The hard Rock Structure ASCII Format uses an hierarchy of the following 6

record types:

FLT - Fault Structure RecordFAB - Fabric Structure RecordVEI - Vein Structure RecordMNL - Mineral List RecordVNM - Vein Fill Mineral RecordRRM - Reaction Rim Mineral Record

Fault Structure Records are used to describe faults and related structures: joints

and shears. Fabric Structure Records describe foliation, cleavage, folds, fabrics,

lineations, and contacts. Vein Structure Records describe veins, dikes, and sills.

Each of these three records, FLT, FAB, and VEI are parent records and may op-

tionally have multiple child records. The child records are the MNL Mineral List

Records, VNM Vein Fill Mineral Records and RRM Reaction Rim Mineral Records.

The number of associated child records of each type is always indicated in a field

of the parent record, and they must immediately follow the parent record.

If the user can make only a single selection from a set of choices, then the field

is an integer, and the key indicates the number assigned to each possible choice.


an array of Booleans, represented by 1’s and 0’s (0 if not selected, 1 if selected).

The array of possible choices is numbered 1 to 16 (or 32), from left to right. For

example: 0101000000000000 indicates that choices 2 and 4 have been selected. All

Boolean arrays are either 16 or 32 in length, and the key indicates the array posi-

tion assigned to each choice. Any unused positions should be recorded as 0 on input

and output.
