Question

Using the information presented in the lab manual and your previous assignments, list the geological events in order from oldest to youngest in the space provided on page 3. Make sure to explain all geological events (i.e. deposition, intrusion, as well as faulting, tilting, erosion (producing unconformities)...etc.) and your best interpretation for geologic environment during genesis (12 marks)

Answer 1

FROM OLDEST TO YOUNGEST

D J I A G B E C F H

Deposition of sedimentary rock layer D is the oldest here over which other layers J I A G deposited conformably over in a sequence and then the whole sequence got tilted after the tilting of these layers an Igneous pluton B intruded the whole sequence making a cross-cutting relationship with these sedimentary rocks after that erosion happened in the region making an unconformity over which after a geologic break sedimentary rock sequence E and C deposited and then the whole succession is intruded by a dike F which is showing cross-cutting relation with all sequence and finally sedimentary layer H deposited.
