WebDec 4, 2024 · Geologist start with first understanding the small-scale aspects of one rock type. To do this, hand samples (samples of the rock layer that are small enough to be held in one's hand) are used. Here geologists make interpretations about the individual grains such as size, mineral composition, and shape (Heinz and Aigner, 2003). WebVarieties of limestone that contain abundant sand-size allochems like oöids and fossil fragments are, in at least a textural sense, types of sandstones, although they are not terrigenous siliciclastic rocks. Such rocks, called micrites when lithified or carbonate sands when unconsolidated, are more properly discussed as limestones.
