The metal elements of the volcanic-hosted massive sulfide deposit have two sources, the copper and zinc are derived from rhyolitic magmas whereas the lead are probably related to old sediments overlying the rhyolites.(4) It is suggested here that the volcanic rocks hosting massive sulfide deposit in the north Qilian orogen, which are previously considered as a bimodal suite of Neo-proterozoic to middle Cambrian age in a continental rift, are virtually related to subduction magmatism in Ordovician age, and there might have no continental rift magmatism of Neo-proterozoic to middle Cambrian in the north Qilian.

Th/Ta比高(5.0～11.7)，εNd为较大的负值(-2.6～-8.4)，流纹岩的形成可能是两个端元组分混合的过程、或是上地壳混染的结果，形成在活动陆缘环境；(3)北祁连块状硫化物矿床成矿金属物质具有两种来源，Cu、Zn等来源于流纹岩，而Pb的来源可能与古老沉积物有关；(4)本文认为，前人厘定的北祁连新元古代-中寒武纪赋存块状硫化物矿床的大陆裂谷双峰式火山岩应是与俯冲作用有关的奥陶纪火山岩，说明北祁连可能不存在新元古代-中寒武纪的大陆裂谷活动。

Gas chromatography with sample-pretreatment by solid-phase micro-extraction and with pulse flame photometric detection was applied to the determination of 6 stenchy sulfides(hydrogen sulfide,carbon disulfide,methanethiol,1,2-ethanedithiol,dimethylthioether and carbonyl sulfide) in polluted air.

Effect of sulfurization time, water content, oil as well as sulfur on spontaneous combustion of iron sulfide is investigated on the same sulfide formed from Fe2O3. It indicates that long sulfurization time, some oil, sulfur as well as good ventilation condition could accelerate oxidation and temperatures rise, but uncertain water content and poor ventilation condition lessen the spontaneous combustion tendency.

以Fe2O3的硫化产物为典型样品，研究了硫化时间、水分、油品、硫及通风条件对硫化铁氧化升温特征的影响，结果表明，硫化时间长，适量的油品和硫以及良好的通风条件能够加速硫化铁升温过程，而一定的水分及不良的通风条件则降低了硫化铁的自燃倾向性。
