What is the difference between Biogenous and Lithogenous?

Lithogenous sediments are formed due to the weathering (wind, rain, freezing) process. This sediments consists consists of small particles of oceanic volcanoes and weathered particles as a result of ionic bond between the metals and silicate ions while b iogenous sediments as the name suggests is as a result of insoluble remnants of past life such as both, teeth and shells. The main types of biogenous sediments are Calcareous (calcium carbonate) and siliceous (silica).
