Biomicrite is analogous to a siliciclastic wacke, sand imbedded in a lot of matrix. If, on the other hand, the depositional environment has strong currents, only allochems may be deposited. If we could see the sediment during deposition all the allochems would be loose, like a pure sand or gravel. This is analogous to a 100% siliciclastic sand ...sparse biomicrite have the same characteristics as the pelagic mudstone microfacies and microbreceia microfacies (SMF 3 and 4). Paleobathymetry shows an increasmg depth due to the sea level rise from the middle shelf-upper slope to the upper slope-lower slope. The compilation of SMF type and paleobathymetry shows changes in the depositional

Hummocky cross-stratification is a type of sedimentary structure found in sandstones. It is a form of cross-bedding usually formed by the action of large storms, such as hurricanes. It takes the form of a series of "smile"-like shapes, crosscutting each other. It is only formed at a depth of water below fair-weather wave base and above storm ...A biomicrite is a limestone composed of fossil debris ("bio") and calcium carbonate mud ("micrite"). Most of the fossil debris in chalk consists of the microscopic plates, which are called coccoliths, of microscopic green algae known as coccolithophores .
