Overview
1.The rocks and sediments that fill in the Gulf of Mexico, especially for Miss.-Louisiana-Texas, can be broken into three main types of rock units, based on the dominant rock type (relates to how the dominate rock type formed). a) What are these three rock types (in order from oldest to youngest) and provide a brief description of how they formed. b) The first (oldest) unit is important in the petroleum industry due to the structures it forms in the subsurface. Explain how these structures formed and why they influence hydrocarbon exploration. (Hint: it’s not just one feature that results from this unit---do other structures or geologic features form as a result that may influence hydrocarbon accumulation?).
