In petroleum geology , the maturity of a rock is a measure of its state in terms of hydrocarbon generation. Maturity is established using a combination of geochemical and basin modelling techniques. Rocks with high total organic carbon , termed source rocks , will alter under increasing temperature such that the organic molecules slowly mature into hydrocarbons see diagenesis. Source rocks are therefore broadly categorised as immature no hydrocarbon generation , sub-mature limited hydrocarbon generation , mature extensive hydrocarbon generation and overmature most hydrocarbons have been generated.
Figure 1. The White House shown in figure 1 is the official home and workplace of the President of the United States of America. Why do you think the White House is white? Construction for the White House began in Its outside walls are made of the sedimentary rock sandstone. This sandstone is very porous and is easily penetrated by rainwater. Water damage was common in the early days of construction for the building.
In sedimentary geology , maturity describes the composition and texture of grains in clastic rocks , most typically sandstones , resulting from different amounts of sediment transportation. A sediment is mature when the grains in a sediment become well-sorted and well-rounded due to weathering or abrasion of the grains during transport. There are two components to describe maturity, texture and composition.
