            The article Technical Announcement: Map Shows Contents and Origins of the Nation’s Geologic Basement by The US Department of the Interior and US geological Survey delivers the composition of earth’s crust (2015). The different pieces are available and succinct in showing the range of the most ancient to recent depictions of events that influenced the composition. They are vital in the development of assessments regarding the mineral resources within the country’s layers originating from the source rocks. In the traditional setting, scientists have been known to determine the entire composition of mineral resources by adjudging clues on the earth’s surface. With the addition of eighty crusts’ pieces to the national basement, the three point six billion years of earth’s preservation forms have accounted for the changes in composition. The maps then deliver the ideal transformation of basement rocks into original metals that were made available through concentration and remobilization from the ore deposits. The users are then able to configure the rocks, mineral sources, and composition forms with the help of deposit types and metal specification. In addition to the information provided the templates for correlation to regional and national faults responsible for even the earthquakes patterns be also explained. The crystalline rocks that lie above the mantle are usually basement rocks and are beneath sediments. Despite the occasional exposure to the surface, they usually exist in miles of rock under rocks as well as sediments. Geological survey facilitates their mappings.

            The article is most closely associated with chapter one of the course material due to the explanation given on mineral and rocks. They form part of the earth’s surface and their composition makes up for the mineral resources obtained. Subsequent action on their mobilization and sedimentation explains the existence of source rocks.
