The indicator texture ofdirect biomineralization is biological organic colloid texture, and the indicator texture ofindirect biomineralization is "mineralized biological texture".

The biomineralization of base metal deposits and its geological characteristics are discussed.

As biometallogenesis is a developing process together with geological processes,this paper mainly deals with migration and reduction by organic matter and organic fluid derived from bacteria and algae.

Reviews on the achievements of microbial metallogenesis in some typical ore depositswith various mineral elements are given, including Fe,Mn,Au,Cu,Pb,Zn,etc.
