为明晰东海盆地丽水凹陷古新统月桂峰组、灵峰组、明月峰组烃源岩的生烃潜力,基于24个泥岩样品主量和微量元素地球化学研究,剖析了古气候和古环境变化过程及其对有机质富集的影响.结果表明,丽水凹陷古新统沉积物相对贫碎屑组分、富自生组分,且主量和微量元素变化未受到成岩蚀变的影响.根据特征元素参数的垂向变化趋势,认为丽水凹陷古新世月桂峰组→灵峰组→明月峰组沉积时期,古气候经历了温湿→干旱→温湿、水体古盐度经历了半咸水→咸水→淡水、水体古深度经历了较深水→较浅水→浅水、水体还原程度经历了弱还原-还原→氧化→弱氧化-氧化的变化过程.古气候和古环境协同变化控制着沉积物有机质生产和保存/降解,是月桂峰组、灵峰组、明月峰组泥岩有机质富集程度存在差异性的主要原因.月桂峰组泥岩形成于温湿气候下的半深湖-深湖环境,水体生产力高,大量藻类和高等植物有机质在分层的贫氧水体介质中得以保存,导致有机质丰度较高.灵峰组泥岩形成于干旱气候下的滨浅海环境,水体生产力低,高盐度且富氧水体介质不利于藻类生存与保存,导致有机质丰度较低.明月峰组煤系泥岩形成于温湿气候下的海陆过渡环境,地表植被发育,地势平坦适宜大量高等植物有机质堆积,形成煤岩与泥岩互层分布.丽水凹陷油气勘探应围绕有机质丰度高且生烃能力强的月桂峰组生烃中心选择有效构造或岩性圈闭进行钻探.

渤海海域秦南凹陷勘探程度低,亟需开展各洼陷烃源岩生烃特征的精细研究以揭示油气勘探潜力和勘探方向。基于地质类比方法,在合理选择地质模型及地质参数的基础上,利用BasinMod盆地模拟软件重建了秦南凹陷各洼陷烃源岩埋藏史、成熟度史和生烃史。结果表明,受差异性沉降和沉积的控制,东洼烃源岩成熟时间早且持续成熟时间长,现今已进入成熟—高成熟阶段(R_(o)=1.0%~2.0%),2次生烃作用分别发生在渐新世和中新世至今,生烃能力强;东南洼烃源岩成熟时间晚且持续成熟时间短,现今已进入中成熟阶段(R_(o)=0.7%~1.0%),主要生烃作用发生在中新世晚期至今,生烃能力强;西洼烃源岩普遍处于低成熟阶段(R_(o)沙一段>东三段。秦南凹陷具有较好的油气勘探潜力,应紧紧围绕东洼和东南洼洼槽带及其斜坡带油气运移优势指向区选择有效圈闭进行钻探。

A comparative study for two different series, La0.67Ca0.33Mn1-xCrxO3 and La0.67＋xCa0.33-x Mn1-xCrxO3 is performed with x changing from 0.04 to 0.08 through measurements of zero-field resistivity （p）, magnetoresistance （MR） and ac susceptibility （Z） as functions of temperature （T）. For the second group, a single insulator-metal transition was characterized by the resistivity maximum appears in p vs. T curve. For the first group, besides the resistivity peak appearing at higher temperatures, the sample shows evidence for the existence of another peak appearing at lower temperatures. Compared to the first group, the second group shows a significant enhancement in MR effect, while the measurement ofΧ-T dependence does not display obvious differences for the two series. Different behaviors observed in the two series are discussed by considering possible exchange interaction between Mn^3- ion and Cr^3- ion.

Attribution of Biases of Interhemispheric Temperature Contrast in CMIP6 Models

引用

Advances in Atmospheric Sciences 2024年第2期41卷 325-340页

作者： shiyan ZHANG Yongyun HU Jiankai ZHANG Yan XIA Laboratory for Climate and Ocean-Atmosphere Studies Department of Atmospheric and Oceanic SciencesSchool of PhysicsPeking UniversityBeijing 100871China College of Atmospheric Sciences Lanzhou UniversityLanzhou 730000China School of Systems Science Beijing Normal UniversityBeijing 100875China

One of the basic characteristics of Earth's modern climate is that the Northern Hemisphere(NH) is climatologically warmer than the Southern Hemisphere(SH). Here, model performances of this basic state are examined using simulation results from 26 CMIP6 models. Results show that the CMIP6 models underestimate the contrast in interhemispheric surface temperatures on average(0.8 K for CMIP6 mean versus 1.4 K for reanalysis data mean), and that there is a large intermodel spread, ranging from -0.7 K to 2.3 K. A box model energy budget analysis shows that the contrast in interhemispheric shortwave absorption at the top of the atmosphere, the contrast in interhemispheric greenhouse trapping, and the crossequatorial northward ocean heat transport, are all underestimated in the multimodel mean. By examining the intermodel spread, we find intermodel biases can be tracked back to biases in midlatitude shortwave cloud forcing in AGCMs. Models with a weaker interhemispheric temperature contrast underestimate the shortwave cloud reflection in the SH but overestimate the shortwave cloud reflection in the NH, which are respectively due to underestimation of the cloud fraction over the SH extratropical ocean and overestimation of the cloud liquid water content over the NH extratropical *** that underestimate the interhemispheric temperature contrast exhibit larger double ITCZ biases, characterized by excessive precipitation in the SH tropics. Although this intermodel spread does not account for the multimodel ensemble mean biases, it highlights that improving cloud simulation in AGCMs is essential for simulating the climate realistically in coupled models.

为揭示东海盆地椒江凹陷油气勘探潜力,基于地球化学和盆地数值模拟方法对古新统月桂峰组、灵峰组和明月峰组烃源岩开展生烃能力和生烃过程研究.结果表明,月桂峰组和灵峰组泥岩有机质丰度高,以II型干酪根为主,为水生生物和陆源高等植物混合来源,且形成于偏还原环境.夹有薄层炭质泥岩和煤的明月峰组泥岩有机质丰度低,以III型干酪根为主,为陆源高等植物来源且形成于氧化环境.古新世至始新世,椒江凹陷大幅度沉降且古热流较高,是古新统烃源岩热演化程度增加的主要时期.受埋藏史和成熟度史共同控制,月桂峰组和灵峰组经历了2次生烃作用,第1次发生在古新世晚期,第2次发生在始新世中期至晚期,生烃强度高.明月峰组仅在始新世末期经历了1次生烃作用,生烃强度低.椒江凹陷古新统烃源岩生烃潜力强,具有广阔的油气勘探前景,应围绕生烃中心尤其是月桂峰组生烃中心选择形成于中新世之前的有效圈闭进行钻探.
