The alteration of iron-bearing minerals induced by hydrocarbon microseepage above oil/gas reser- voirs has been evaluated using measurements of soil magnetic susceptibility k, geochemical compositions (gas hydrocarbon and alteration carbonate △C), and composition and concentration of iron-bearing minerals. The analyses were performed along two profiles across the Qiangtang basin in Tibet, China: the Nuoermahu-Xuehuanhu profile (c) and the Mugari-Huochetoushan profile (E).
