What would be the best strategy to use to find a mineral deposit that has been buried by a thick section of younger sediments?
A) closely examine rocks on the surface
B) study how much soil has developed on the surface
C) begin drilling in any site just to see what is down there
D) conduct some type of geophysical survey
Mineral Deposit
A natural accumulation of minerals in quantities sufficient for economic extraction.
Geophysical Survey
The use of one or more geophysical techniques to explore Earth’s subsurface, including seismic, gravity, electrical, magnetic, radioactivity, and heat-flow measurements.
Younger Sediments
Sediment layers that have been deposited more recently over older layers in the geological strata.

Final Answer :
D
Explanation :
Geophysical surveys are the best strategy for finding mineral deposits buried under thick sections of younger sediments. These surveys can detect variations in the Earth's physical properties (such as magnetic, gravitational, electrical, and seismic properties) that indicate the presence of mineral deposits without the need for immediate, invasive drilling.
