Geology Field Visit - The Untold Stories of Rocks

Field visits are a crucial component of geology instruction. They are essential in assisting students learn about, comprehend, and appreciate the many geological formations and aspects. The primary goal of the visit was to introduce the students to the various rock types, geological features and structures, and lithologies. 

A particular focus was placed on the geology of the rock structures, including folds, faults, and structural characteristics such bed strike and dip. in short, Geology Field Visit is a type of study trip in which various case are being discovered and performed practically.

 

Geology Of Nizampur Basin

The  Nizampur  basin  is  located  in  the  vicinity  of  the  Attock  city,  Punjab, Pakistan along  its  southern  margin. To  the  north  of  the  Nizampur  Basin  lies  the  Attock  Cherat  Range,  thrusted  by  the  Hisartang fault;  while  it  is  bounded  in  the  south  by  Kala Chitta  Range. 

The Nizampur is a section of the thrust and fold belt that runs along the Himalayas. There are numerous thrust faults and various folds in the region, which has a complex geological structure. The region is heavily broken, and the pattern of the fractures suggests numerous episodes of deformation.

The sandstone and sandy limestone facies make up the majority of the series. It denotes a coastal to inner shelf location with a moderate to high energy level in the Kahi village sector.

   

Geology Field Trip to Nizampur - The Story

On 13, May, 2022, our field trip was arranged to the Kala Chitta Range and Nizampur basin by Geology Department, University of Peshawar. In Nizampur trip, we study the geological nature of various rocks native to Nizampur, Punjab, Pakistan. It was hot summer, when we embark on the geological field trip to Nizampur.

The sun was blazing on peak but still we, the students of geology Department, enjoy our trip a lot and discover new things on this geo location. Along with studying geology, we make some priceless, everlasting memories with friends and classmates.

One thing I learn from these geological field visits is that, not only books are important for education but practical work is essential for better learning and understanding the basics of field study.

 

Geological Structure of Nizampur

    Our first field trip where the emphasis was mainly on structure geology was this one. The Attock Cherat Range lies to the south, and the Kala Chitta Range is to the north, of the Nizampur Basin. The Indus River borders it on its east, and the footwall of the Hisartang fault is where the Attock Cherat and Kala Chitta Range meet.

The Eocene-aged Margilla Hill Limestone is the youngest rock unit found in the Nizampur Basin, and the Jurassic-aged Samana Suk formation is the oldest rock unit exposed there.

    The sequence is normal from younger to older rocks until the Kawagarh Formation, after which it returns to normal until the Lumshiwal Formation as it moves north from the Margilla Hill Limestone in the Kahi Valley area. The Samana Suk formation is repeated, which indicates the presence of a subsurface fault.

Synclines, anticlines, conjugate fractures, folds, and other structural geology features were also seen.Additionally, we learned how to use a Silva compass to gauge a bed's quantity and direction of dip.

    In  this  field  trip  we  studied  the  syncline  within  the  Margalla   Hill  limestone, on  top  of  the  Patala  shales. We  observed  conjugate  fractures,  folded  strata,  and  thrust  faults  within  Nizampur  Basin.
