Questions and Answers

What type of grains were primarily found in the Murray Formation sediment by Rivera-Hernández et al.?

Silt grains

Mixed grains

Fine grains (correct)

Coarse grains

What conclusion did Rivera-Hernández et al. draw about the coarse grains found in the Murray Formation?

They are sandstone deposited by flowing water. (correct)

They are indicative of volcanic activity.

They represent sediment from glacial movements.

They are a result of wind erosion.

What characteristics did the fine grains exhibit in the Murray Formation sediment?

Signs of cracking due to episodic desiccation. (correct)

Evidence of rapid volcanic deposition.

Inclusion of large mineral fragments.

Presence of fossilized microorganisms.

Study Notes

Data from Mars Rover Curiosity

Data suggests hydrological deposition of sediment in the distant past at Gale Crater's Murray Formation
Analysis of grain size from Murray Formation sediment shows fine grains, with some coarse grains indicative of episodic drying
Coarse grains likely sandstone (deposited by flowing water)
Fine grains likely mudstone (deposited by slow-moving water/low flow)

Completing the Text

Correct answer: A lake existed at the Murray Formation for a prolonged period, but there were periods with intermittent drying and streams
