1 噻吩类化合物的检出广西金牙金矿为一大型微细浸染型金矿床,含矿的中三叠统百逢组为一套浊积岩,以富含有机质的泥质、粉砂质混积岩为主.矿体产出特征沿走向和倾向均严格受断层破碎带控制,产出在百逢组的破碎带中.通过对矿体与围岩有机地球化学的对比研究,在芳烃组分气相色谱-质谱谱图上检出了7种噻吩类化合物(或含硫芳烃):苯并[b]萘[2,1-d]噻吩、苯并[b]萘[1,2-d]噻吩、苯并[b]萘[2,3-d]噻吩、4-甲基二苯并噻吩、2+3-甲基二苯并噻吩、1-甲基二苯并噻吩
1 Detection of Thiophene Compounds The gold tooth gold deposit in Guangxi is a large-scale finely disseminated gold deposit. The Middle Triassic Baifeng Formation in the ore-bearing area is a set of turbidite rocks. The muddy, silty- The main characteristics of the ore bodies are along the strike and trend of the ore body output.It is strictly controlled by the fault zone and produced in the crustal zone of the Baifeng Formation.Comparing the organic geochemistry of the orebody and the surrounding rock, Seven kinds of thiophene compounds (or sulfur-containing aromatics) were detected by gas chromatography-mass spectrometry: benzo [b] naphthalene [2,1-d] ] Thiophene, benzo [b] naphtho [2,3-d] thiophene, 4-methyldibenzothiophene, 2 + 3- methyldibenzothiophene, 1-methyldibenzothiophene
