冀东迁西三屯营地区的高级变质杂岩,主要由早太古宙的三组片麻岩所组成。岩石地球化学研究表明,较早期的三屯营片麻岩为钙碱性石英闪长质岩石,除U和Th外,它不亏损不相容元素。较晚期的小关庄片麻岩和秋花峪片麻岩,分别为钙碱性石英闪长质和钙碱性英云闪长—奥长花岗质岩石,二者均发生了不相容元素的亏损。三屯营地区的岩石亏损与未亏损是源岩浆所具有的特征,可能是初始地壳形成时上地幔不均匀造成的。

我们利用holland和powell(1990)的内部一致的热动力学数集,在0～18kb,460～720℃温压范围内计算出了KFMASh(K_2O—FeO—MgO—Al_2O3—SiO_2—h_2O)体系和KFASh、KMASh亚体系中的单变平衡线和不变平衡点,这些体系中含有十字石、硬绿泥石... 详细信息

我们利用holland和powell(1990)的内部一致的热动力学数集,在0～18kb,460～720℃温压范围内计算出了KFMASh(K_2O—FeO—MgO—Al_2O3—SiO_2—h_2O)体系和KFASh、KMASh亚体系中的单变平衡线和不变平衡点,这些体系中含有十字石、硬绿泥石、绿泥石、黑云母、堇青石、石榴石、红柱石、矽线石和蓝晶石组合及过剩的白云母、石英和水。我们不仅获得了这些平衡的温压位置,而且还确定了涉及到MgFe—1和MgSiAl—2置换的矿物成分。除了在我们的KFMASh体系格子中由于没有Fe^(+3)而无硬绿泥石+黑云母或红柱石+黑云母组合的稳定范围以外,harte和hudson(1979)所确立的岩石一致格子是特别出色的。但考虑到格子中反应位置的不确定性以及黑云母和硬绿泥石可能富集了更多的那部分Fe,这些组合在格子中即是稳定的。我们检验了一个内部一致的数集是否象我们合理预测的与那些天然泥质岩石一样复杂的相关系,尽管结果与岩石学观察是有惊人的一致性,但仍需进一步的实验工作,特别是含堇青石和十字石的反应,在进一步改进以前。

土地管理方式深刻影响着生态系统过程及其功能,尤其是在干旱生态系统,养分和水分的亏缺可通过直接影响生态系统生产力和间接影响土壤生物,继而影响着生态系统的功能属性。植物根系和土壤中的真菌在土壤养分循环和植物营养获取方面发挥着关键作用,然而对于干旱区森林生态系统中真菌如何响应土地管理措施的认知仍亟待加强。我们研究了长期（6年）灌溉和施肥条件下,桉树（Eucalyptus saligna）林中两种微生境（林下草本植物存在（远离桉树）和不存在（靠近桉树））中,其根系和土壤中真菌群落的响应变化。研究发现,真菌的物种丰富度和均匀度（α多样性）在土壤中显著高于根系;灌溉和施肥处理对真菌α多样性的影响不明显,但显著性影响真菌的β多样性（群落组成）;土壤p h、湿度、速效氮含量是影响真菌群落组成的主要因子。施肥和灌溉降低真菌中外生菌根真菌的比例,但增加腐生和（或）植物病原真菌出现的几率。施肥降低桉树根系和土壤样品共同拥有的真菌分类单元（OTU）的出现频率,表明施肥弱化根系和土壤中真菌群落的关联度。此外,相对于有草存在条件,在无草存在的微生境中,桉树根系和土壤之间真菌OTU共发生的紧密度相对较低。该研究强调森林管理措施对于土壤真菌群落的构建至关重要,将影响到对真菌群落动态和养分循环的预估能力。

肉样瘤病误为子宫内膜癌复发

世界核心医学期刊文摘（妇产科学分册） 2006年第4期2卷 47-48页

Background. Sarcoidosis is a multisystem disease and can be confused with benign or malignant tumors. In patients with recurrent gynecologic cancer, liver and intrathoracic lesions should undergo a biopsy to rule in metastatic malignancy, as clinical findings and CAT scan results may represent other disease processes. Case. A 67 year old woman had a total abdominal hysterectomy, bilateral salpingo-oophorectomy, pelvic and periaortic lymphadenectomy, and peritoneal cytology in 2001 for Stage I B grade 1 adenocarcinoma of the endometrium. She developed a vaginal recurrence in 2005. A CT scan of lungs, abdomen, and pelvis revealed extensive mediastinal adenopathy and multiple space occupying hepatic lesions worrisome for metastatic disease. A needle biopsy of the largest liver lesion revealed sarcoidosis. Conclusion. Sarcoid lesions may mimic metastatic disease in patients with malignancy, potentially leading to delayed and/or inappropriate therapy.

许多太古代绿岩金矿、维特瓦特斯兰德金矿、板岩带金矿及浅成热液金矿的形成与低盐度、高温(>200℃)还原流体有关。这种含金流体出现在不同时空、岩石序列及构造背景中,是镁铁质岩和/或杂砂岩变质去挥发分作用的产物。绿泥石-钠长石-方解石-石英组合(如镁铁质岩或杂砂岩),在绿片岩-角闪岩相边界发生的变质作用(约480℃±20°,3～5kbar)产生大量低盐度h_2O-CO_2流体,其成分与许多金矿床已查明的流体相似。流体含还原硫(由黄铁矿溶解提供),具备Au呈Au-S络合分子搬运的理想条件。金的沉淀可以因温度、硫活度降低及氧活度变化实现。变质去挥发分流体模式解释了主要金省之共性(如高地热梯度、低盐度以及与变质作用大致同时),也说明了容矿岩石与构造、具体时序关系、蚀交组合以及不同矿床地质年龄之多变性。相似性是由深部过程产生,而差异性则是由沉淀位置或其附近的作用造成。

A superior homonymous quadrantanopia is a well recognized complication of anterior temporal lobe resection and occurs because of disruption of the Meyer loop, the anterior part of the optic radiation. The authors used diffusion tensor imaging tractography to visualize the optic radiation before and after surgery, demonstrating the disruption of Meyer loop in a patient who developed a quadrantanopia. Preoperative imaging of the optic radiation will be useful in predicting visual field defects following temporal lobe resection.
