The subject of this question is Geology, specifically the dominant lithologies in the Triassic and Jurassic time periods and the reasons for the change in lithology.
The subject of this question is Geology.
The question is asking about the dominant lithologies in the Triassic and Jurassic time periods, and why the lithology changed between these two periods.
In the Triassic, the dominant lithology is red shale, salt, and basalt.
This is indicated by the presence of Triassic red shale, salt, and basalt in the Pre-Mesozoic basement.
In the Jurassic, the dominant lithology is hintalo sandstone, which is represented by Upper Lias-Dogger shale and limestone and Lower Lias limestone and dolomite.
The change in lithology between the Triassic and Jurassic can be attributed to geological processes such as deposition and erosion, as well as changes in environmental conditions.
