同生矿床-
同生沉积矿床在变形变质过程中的再活化，会在矿床中产生许多后生特征，这一点在研究矿床成因时必须充分注意。
Reactivation of the synsedimentary deposits during deformation and metamorphism would add many epigenetic features to the deposits , which should be paid more attention during research .

而热卤水同生沉积型矿床中，Ba的含量特别高，它可作为海底热液活动的证据之一及寻找此类矿床的地球化学指标。
However , Ba content is very high ( > 2000 × 10-6 ) in Ag-Pb ore deposit of thermal brine and syngenetic type . It is therefore feasible to regard the anomaly of Ba in rocks as one of the evidences of submarine hydrothermal activity and a geochemical indicator .
