In abundance.
(Konzentrat-Lagerstätten) - fossil deposits where occurrence is remarkable because of the sheer abundance of specimens.
A mineral deposit's abundance in a specific location is influenced by various factors such as geology, tectonic activity, and geological history. The Philippines is located in a region with complex geology and active tectonic settings, which have created favorable conditions for the formation of various mineral deposits. Additionally, the country's geological history, including past volcanic activity and the presence of mineral-rich belts, has contributed to the abundance of mineral deposits in the Philippines.
The fossil fuel found in greatest abundance in Virginia is coal. Virginia has large coal deposits that have been historically important in the state's economy.
The north had more iron ore deposits compared to the south. The Iron Range in Minnesota and regions in Michigan were known for their abundance of iron ore deposits, which played a significant role in the industrial development of the northern states.
Thorium is found in abundance along the western coast of India, particularly in the coastal regions of Kerala and Tamil Nadu. The Monazite sands along this coastline are rich in thorium deposits.
Sandstone.
Cassiterite is the primary ore of Tin, the mineral is found in hydrothermal veins and pegmatites associated with granite intrusions. Because of its durability it is also frequently found concentrated in alluvial placer deposits, often in large enough quantities to be commercially exploitable all over the world.
In the context of mineral deposits, "rich" means that the area or deposit contains a high concentration or abundance of valuable minerals such as gold, silver, copper, or other economically significant minerals. It indicates that the location has a high potential for mining or extracting valuable resources.
Calcium from the Latin word calcis.
