Generally the connate is called the set of organs, they are linked together, since they are born together. In other words, they are a series of organs of the same classification that are united in a natural or congenital way. connate is a term used in botany to refer to this meaning, that is, they are organs or structures that are more or less united to each other. And an example of this resides in those opposite leaves that are joined at their bases, each filament of the anthers, which is the terminal part of the stamen of a flower, or the members of the calyx (extreme whorl with heteroclamidic perianth) or of the corolla (internal whorl of flowers that have heteroclamidic perianth), which may be separated from each other or joined together, which is what is called connate.
On the other hand, in geology and sedimentology, it is known as connate fluids to the liquids that are trapped in the pores of the sedimentary rocks that were deposited. These liquids are composed mostly of water, but they also contain many mineral components such as ions in solution. And since they are buried in rocks or stones, they undergo lithification and the connate fluids are generally expelled. If the escape path for these fluids is blocked, pore fluid pressure can build up, leading to overpressure.
An understanding of the geochemistry of connate fluids is of utmost importance if rock diagenesis is to be quantified. Solutes in connate fluids often precipitate and reduce the porosity and permeability of the host rock, which can have important implications for its hydrocarbon prospectivity.
