| 英文摘要 | Yanliao Mesozoic (189 similar to 120Ma) volcanic rocks in North China Craton are composed of basalt-andesite-tracbyte-rhyolite associations. Petrographically, Mesozoic volcanic rocks have porphyritic textures with phenocryst minerals of olivine, pyroxene, amphibole, biotite, plagioclase, alkali feldspar, quartz and Fe-Ti oxides setting in the groundmass of amphibole, biotite, plagioclase, alkali feldspar, quartz and glass. Maximum heights of the Mesozoic volcanic eruption columns in the Yanliao area are above 18 km based on the physically volcanologic modeling calculations, which have been considered to entering into the stratosphere. Electron microprobe and infrared ray spectrum analyses determined contents of major elements and volatiles (including Cl, F, S, CO(2), and H(2)O) of magma inclusions in the phenocryst minerals and groundmass glass of the Mesozoic volcanic rocks in Yanliao. The analysed results show that volatiles emitted are variable during the Mesozoic Yanliao volcanism from early to late. Volatiles released from Nandaling basaltic volcanic activities ( similar to 188Ma) in the early stage are enriched by S and Cl, possibly declining Earth's surface temperatures and forming acid rain. Volcanic degassing of Tiaojishan andesitic and trachyandesitic volcanism (174 similar to 161 Ma) is characterized by enrichments of H(2)O and CO(2), which has increased Earth's surface temperatures. Zhangjiakou trachytic and rhyolitic pyroclastic flows and lavas (148 similar to 141 Ma) have erupted a large amount of Cl and F into the atmosphere, which resulted in acid rain and ozone depletion, Volatiles from the Yixian-Jiufotang intermediate and acidic volcanic rocks in the western Liaoning province (135 similar to 120Ma) have high concentrations of S, F and Cl, leading to mass mortality events. |
