Nothing big not a geologist or anything just a student that wanted to learn the prosses of how Kerogen is made and you explained it very well. Thanks for making this video
Sir your explanation is really wonderful, it helped a lot. Sir for hydrocarbon exploration what implications or indicators can we get to interpretate them?. And why in many basins we dont get such reserves of hydrocarbon, can we assume the absence of biota there or something else?
It is a good question. For HC exploration there are various indicators which include the TOC, vitrinite reflectance, seismic indicators for the regional structure, well logs for the lithological interpretations and bole hole geometry. We shall discuss those when I do the HC exploration lectures. Now regarding basins, the HC potential of a sedimentary basin is closely related to its tectonic history, sediment depositional history as well as organic matter content. It is quite possible that a basin had high organic matter content but in due course of time it got destroyed due to decomposition, erosion, or even metamorphism. Take example of the Tethys Ocean. As India collided with Eurasia, the Tethyan basin closed and Himalayas rose which cause intense metamorphism. It destroyed the organic matter deposited in the sediments which formed Himalayas. While the region of the GUlf countries have high petroleum reserves due to their high organic content which got preserved in their sediments. The Mediterranean Sea which is the remnant of the Tethys has high OM preserved in its sediments. This high OM is a major region for high petroleum reserves in the Gulf countries. India has 26 sedimentary basins but not all of them have potential to produce HC and a major factor is the either the loss or absence of OM in those sediments.
Since u mentioned sir that hydrocarbon can exist in gaseous form solid .liquid and plastic . I'm well know of three states of matter solid liquid and gase.but who also mentioned plastic form of hydrocarbons . What kind of form is it? Plz explain
@@MrVikramsingh1 that means the state in which asphalt exist is plastic is it? And is this state only confined with hydrocarbon that's solid liquid gase and plastic ? And can u plz mention which state we define as plastic i I mean by solid we means something that has rigidity hight melting point etc and liquid and gas have their own characteristics .in the same way what is plastic ? What are its characteristic ? Plz explain
@@DanishLone-s5p it’s not exactly plastic. Rather it has a glassy solid texture. It exists from very viscous liquid to glassy solid. Asphalt is formed in the last stage of maturation of kerogen, at very high temperatures and is not an economically viable fuel.
Sir I want to ask u a different question which is not relevant to this topic the question is since we know about clay minerals they are phyllosilicate and and are formed by chemical weathering of silicate minerals . Also i know mica serpentine chlorite talc and clay all are phyllosilicate silicate .but the confusion I have is many books mention chlorite and mica under a 2:1 type of clay . Sir plz tell me is mica and chlorite a type of clay or seperate minerals which also undercomes phyllosilicate plz explain in detail
@user-ne1hj6sd6s first of all you should understand that phyllosilicate is a type of silicate group which has various types of minerals like the mica group, chlorite, kaolinite, montmorillonite, etc. The mica group is an important component of granites and metamorphic rocks. So it cannot be essentially called a clay mineral. So what is it that we can classify as clay minerals? Remember, clay a product of weathering which is formed by successive weathering of the rocks. Certain minerals who care formed during the successive chemical leaching/weathering of the minerals of hard rocks give rise to a new set of phyllosilicate minerals like chlorite, montmorillonite, smectite etc. These minerals have structure made of tetrahedral and octahedral sheets which are arranged as 1:1 or 2:1. They have the hydrous aluminium silicate as an essentials component, with varying concentration of Fe, Mg, alkali metals or alkaline earth metals
This is so helpful. Am a geology student from Zimbabwe 🇿🇼 and your teachings took me heights in knowledge. Thank you!

Please don't stop making videos...It helps a lot for geology students
Thanks for your demand. I have been very busy with some other work for quite sometime. New videos will come up after September.
Thank u for uploading all these videos
A lot of thanks it's really wonderful explaination ... again I must say thank

Asphalt is the material formed in the last phase of HC generation. It is plastic
@@MrVikramsingh1 that means the state in which asphalt exist is plastic is it? And is this state only confined with hydrocarbon that's solid liquid gase and plastic ?

Sir please make video on principles of stratigraphy( craton )
Ok
Sir pls can you give me a link to your slides
I haven’t uploaded these slides anywhere.
