What is placer deposit in geology?

placer deposit natural concentration of heavy minerals triggered by the impact of gravity on moving particles When heavy steady minerals are devoid of their matrix by weathering procedures they are gradually cleaned downslope into streams that rapidly winnow the lighter matrix.

Why exist big deposits of minerals in the Philippines?

The Philippines is blessed with metal and mineral deposits due to its geology The islands are on the top of undersea mountains that were formed due to the molten rocks from the interior of the earth which produced the perfect setting of a range of important minerals.
