Most Previous HitanhydriteNext Hit classification systems to date have focused primarily on the naming of Previous HitanhydriteNext Hit bodies, masses, or crystals themselves rather than focusing on both the mineral morphology and links to the sedimentary succession in which it occurs. Much of the reasoning for the lack of development of an integrated classification system for Previous HitanhydriteNext Hit may come from the inherent instability of the mineral, and therefore the difficulty making a link between any particular morphology and a specific formative process or environment. This sets Previous HitanhydriteNext Hit classification apart from other sedimentary classification schemes, as most of them (e.g., Dunham, McBride, etc.) naturally break into groups that can be related to sorting, textural maturity, mode of deposition, or other genetic process. A classification system for Previous HitanhydriteNext Hit has been developed that allows for information about the gross Previous HitanhydriteNext Hit volume and morphology, as well as host sediment type to be transmitted using a single type-name.

This new integrated Previous HitanhydriteNext Hit classification scheme was developed using input from both previously developed schemes and field studies with a view to link Previous HitanhydriteNext Hit morphology and volume to precursor depositional process. These relationships have been shown to hold true in certain circumstances, with both gross Previous HitanhydriteNext Hit volume and morphology many times being characteristics that are particular to former depositional setting (bedded, laminated salinic Previous HitanhydriteNext Hit versus nodular sabkha Previous HitanhydriteNext Hit, as an example). By adding a host rock descriptor to the scheme, quite a bit of empirical information about the Previous HitanhydriteNext Hit is made available in a single name, which can then be more easily linked to genetic process. Such a scheme may have wide application in industry, where careful description and classification of Previous HitanhydriteTop is a key component to understanding the distribution of reservoir rock types in the subsurface.
