The Juancheng chondrite──A new meteorite falling recently in China

The Juancheng chondrite, a new meteorite falling recently in Juancheng County, Shandong Province, China, is classified as an H5 (S2) chondrite based on the compositions of olivine (Fa= 19.2, σ Fa=0.46) and low-Ca pyroxene (Fs=16.9, σ Fa=0.4). The plagioclase in the Juancheng chondrite is rich in CaO, indicating a relatively high metamorphic temperature the parent body underwent.     

Discovery of eclogite at northern margin of Qaidam Basin, NW China

Eclogite was first discovered at the northern margin of the Qaidam Basin in this study. It occurs as pods in the gneiss sequence of Middle to Upper Proterozoic age and is mainly composed of garnet, omphacite, phengite and rutile. The garnets contain 44%-62% of almandine, 15%-33% of grossular and 12%-30% of pyrope molecules, and the omphacites contain 40%-46% of jadeite. Applying garnet_clinopyroxene thermometry and jadeite geobarometry, the peak conditions of eclogite facies metamorphism occurred at about (722±123)℃ and at the pressure of up to c. 22 ×10 8 Pa.     

High-precision timing of the Quaternary standard samples with thermal ionization mass spectrometry (TIMS) U-series method

Two national stalagmite standard (GBW04412, GBW04413) and one international coral standard (RKM_4) have been determined by using thermal ionization mass spectrometry (TIMS) method. The values of ( 234 U/ 238 U) act , ( 230 Th/ 234 U) act and age are all consistent in error range with the standard values obtained by using α spectrometry.     

Leakage of mantle helium from the Liaodong Peninsula, China

The isotopic cumpositions of helium have been investigated in hot spring gases sampled from the Liaodong Peninsula. China. The³He/⁴He ratios range from 0.14 Ra (0.14 times the atmospheric³He/⁴He ratio of 1.40 × 10^-6 to 0.72 Ra.³He/⁴He versus⁴He/²⁰Ne ratios and He contents suggest that a small amount of mantle-derived helium reaches the earth’s surface. Helium iwtope ratios of the hot spring gases show a distribution pattern similar to the regional heat flow values, indicating that the positive thermal anomaly occurring in the rtrea is closely associated with the presence of mantle-derived helium. The observations described above provide some significant evidence that the molten magma originating from partial melting of the upper mantle may have intruded into the continental crust along the activity fault. The coupling of the presence of mantle He and heat flow anomalies to seismic activity in studied region seem to imply that there is an internal relationship between mantle degassing and seismic activity.     

温州的垂直绿化植物资源

攀援植物具有生长迅速,又易于栽培管理等特点,是城镇进行垂直绿化的优质材料,可美化环境,改善小气候．据调查统计,温州地区有攀援植物40科235种（变种）左右．这些资源可用于墙面、棚架、栅栏等的绿化,但目前这类资源的利用还很低,尚有许多优良的攀援植物有待进一步开发利用．

杂交玉米酯酶电泳指纹的研究

本文运用聚丙烯酰胺凝胶电泳技术,以杂交玉米种胚为材料,研究制作了八个杂交种及其亲本自交系原种的种胚酯酶电泳指纹,其具有稳定、清晰、特异性强等特点．用其中的丹玉１３（Ｍｏ１７Ｈｔ×Ｅ２８）杂交组合,比较了用电泳指纹法与田间种植鉴定法．经检验人为掺混种子批中母本自交粒比率中的准确度,结果表明：指纹法与实际掺混水平更为接近,比田间种植鉴定的成熟期鉴定结果还要准确
