HOMEWORK HELP PLEASE!

1) The turbidites of the Devil's Slide formation were deposited during the late Paleocene, which means they were deposited long after the dinosaurs had gone extinct but not that long before the formation of the San Andreas Fault around 25 million years ago. The rocks of course began as flat layers, but were moved into their current contorted positions by the motions of the San Andreas Fault.

There are turbidites currently forming now. Where would you find the sediments that are already deposited, and are currently being compressed and lithified into future turbidites?

2) How did the Montara granite rock arrive at Devil's Slide?

3) What is the closest inactive fault to the Devil's Slide formation?

4) What is the closest active fault to the Devil's Slide formation?

Explanation / Answer

After the deposition of the turbidity sediments, there will usually be a more tranquil regime of deposition and the marine clay will be deposited on the top.entire sequence of sediments produced by these two mechanisms is known as bouma sequence.these sediments flows along the bottom of the sea and it leaves ripple marks and because it leaves sole marks gouged out of the previous layer of sediment.These are deposited on the sea floor .direct observation of turbidite formation is the events in Lake Brienz in 1996.sediment cores from lake shows that an abnormal layer of sediment, 90cm thick at its thickest part, had laid down, the sediment graded vertically upwards from sand through silt to clay.

2) It is structurally overlain by marine sedimentary rocks of Tertiary-age.

3) Seal cove fault

4) San Andreas fault
