However, organicmatter only in ore-forming fluids is directly involved in metallogenesis. In this note, a series ofbiomarkers in hydrocarbon inclusions were identified through gas chromatography-mass spec-trometry (GC-MS). Comparison and contrast on extractable organic matter (EOM) was madeamong inclusions, ores and host rocks. Metallogenesis related to EOM was also discussed.展开更多
