INDIAN GEOGRAPHY

Detailed explanation-1: -The process of this salt deforming rock is known as salt tectonics, and take place over hundreds of millions of years. Oil and gas that flows through the reservoir rock will come to rest when it reaches the salt dome and is then trapped.

Detailed explanation-2: -Sedimentary rocks Petroleum may occur in any porous rock, but it is usually found in sedimentary rocks such as sandstone or limestone. Sedimentary rocks are grouped into three major classes: clastic, carbonate, and evaporitic.

Detailed explanation-3: -An anticline is a structural trap formed by the folding of rock strata into an arch-like shape. The rock layers in an anticlinal trap were originally laid down horizontally and then earth movement caused it to fold into an arch-like shape called an anticline.

Detailed explanation-4: -A structural trap is a type of geological trap that forms as a result of changes in the structure of the subsurface, due to tectonic, diapiric, gravitational, and compactional processes.

Detailed explanation-5: -Petroleum source rock is defined as the fine-grained sediment with sufficient amount of organic matter, which can generate and release enough hydrocarbons to form a commercial accumulation of oil or gas [1]. Source rocks are commonly shales and lime mudstones, which contain significant amount of organic matter [2].
