摘要

///Micro-disseminated type magnesium carbonate rock gold deposit in the western Shandong is a newly found gold deposit type after founding of crypto-explosive breccias type Guilaizhuang gold deposit. This type gold deposit occurs in magnesium carbonate rock, such as dolomitite and dolomitic limestone in Early Cambrian Zhushadong formation. Layer orebodies are stable occurrence with simple types. Mineralization is continuous with good ore exploration future. Ore formation are closely related with medium-alkali cryptovolcanic complex in the Early Mesozoic Yanshanian. It is shown that ore-controlling mechanism is combination of monzonitic porphyry, fault and magnesium carbonate rock.
