AcknowledgementThanks to Allah Almighty who gave me strength to be a part of fieldtrip to salt range and gave me sense to understand the demonstration given by teachers at the field, that was organized by Department of Geology University of Haripur and. After that I would like to thanks to my instructors, Sir Salman Khattak, Sir Azeem Shah and Sir Toufeeq Ahmed, who were with us during our field and they helped me a lot during the field trip. I am very thankful to Sir Hammad (Pakistan museum of natural history) for sharing his knowledge about salt range.I Am very thankful to Ahsan Saeed(Seniour) for guidance.

AbstractThe Salt Range contains the most important geologic and paleontological localities in Pakistan, and is one of the outstanding field areas in the entire world. Despite its easy accessibility, it has a wealth of geological and paleontological features. In fact, it represents an open book of geology where various richly fossiliferous stratified rocks are very well exposed due to lack of vegetation. These include the Permian carbonate succession with its outstanding brachiopod fauna, Lower Triassic ammonoid beds (the Mianwali Formation, formerly known as "Ceratite Beds"), and Lower Tertiary marine strata with age diagnostic foraminifera. These rocks also provide an excellent opportunity for appreciation of tectonics in the field. In addition to the easily available roadside geology, some prominent gorges provide fantastic locations to study the sedimentary succession. Older strata are exposed in the eastern Salt Range between the Khewra-Choa Saidan Shah, including the famous Khewra Gorge. In the west, beyond Kallar Kahar, are younger strata such as in the Nilawahan Gorge at Nurpur, the Nammal Gorge near Mianwali.

This succession has been rightly called a Field Museum of Geology and Paleontology and can be classified as one of the great paleontological areas of the world, fully worthy of conservation and protection efforts.

IntroductionWe made a trip to Salt Range on 9 March after terminal exam of third semester, and we left university at about 8:30 Am. It was a 5 day field. We made a stay at Katas Raj youth Hostel and made observations in Khewra Gorge and Stratigraphy exposed along Dandot road. Also we learned how to determine strike and dip using Brunton Compass.

Then we started out journey to Mianwali, while travelling we made several stops along the road side to study the stratigraphy exposed. And in Mianwali, we made stay in a Restaurant. We had a stay of two days over here and here we observed stratigraphy and in few formations we observed palaeontology exposed in Nammal Gorge and Zaluch Nala.

Page 9: Salt Range field Report By Samiullah

Observations:

Stop Number 1: Pidh Choa Saidan Shah Road

Determination of Strike and Dip using Brinton compass:

At this stop we determined how to find strike and dip at the field.

Measuring Strike:

Strike:

Direction of the line of intersection between a tilted plane and a horizontal plane.

Compass must be horizontal (bull’s eye bubble centered), with compass edge flush to the tilted plane

And note the reading. S50E

Measuring Dip:

Dip:

Place compass on its side, perpendicular to strike.

Level the clinometers (center the bubble).

Read the dip.

The Permian–Triassic (P–Tr) extinction event, colloquially known as the Great Dying, occurred about 252 Ma (million years) ago, forming the boundary between the Permian and Triassic geologic periods, as well as the Palaeozoic and Mesozoic eras. It is the Earth's most severe known extinction event, with up to 96% of all marine species and 70% of terrestrial vertebrate species becoming extinct. It is the only known mass

33

Page 34: Salt Range field Report By Samiullah
