District attorneys and prosecutors are fearful of any chance that someone arrested for domestic violence related charges later hurts the victim again. If there is a prior record of an arrest but no charges or prosecution, that fact would be potentially damaging and embarrassing.
Detrital or clastic sedimentary rocks are composed of rock fragments. They are different than chemical sedimentary rocks, which are composed of mineral crystals. Learn how these sedimentary rocks differ in their formation and composition.
Sedimentary rocks are formed by the accumulation of sediments. There are three basic types of sedimentary rocks. Clastic sedimentary rocks such as breccia, conglomerate, sandstone, siltstone, and shale are formed from mechanical weathering debris. Chemical sedimentary rocks, such as rock salt, iron ore, chert, flint, some dolomites, and some limestones, form when dissolved materials precipitate from solution.
