本文首次报道华南古生代武夷-云开造山带东南缘的兰排镁铁-超镁铁质岩体富钪(Sc)风化壳,初步计算获得区域内钪的潜在资源为524~566 t,为一潜在大型风化壳型钪矿。兰排岩体呈小型岩株侵入到永和闪长质岩体内,主要由橄榄岩、辉石岩和辉长岩组成,辉石岩锆石^(206)Pb/^(238)U年龄为(428.3±2.0)Ma(MSWD=0.92)。镁铁-超镁铁质岩全岩w(TFe_(2)O_(3))为12.1%~18.7%,其中辉石岩钪含量为44×10^(–6)~97×10^(–6),总体高于橄榄岩(20×10^(–6)~89×10^(–6))和辉长岩(28×10^(–6)~48×10^(–6))。兰排这类富钪岩石组合与以往认为富钪的碳酸岩-碱性岩体和阿拉斯加型岩体都存在较大差异,可能代表了一种新的钪成矿母岩类型,推测碰撞后陆内伸展诱发富钪地幔源区熔融可能是富钪母岩浆形成的重要机制。镁铁-超镁铁质岩体上部发育完整的风化壳剖面,可分为全风化层和半风化层。全风化层的上部富集铁(氢)氧化物(磁铁矿、赤铁矿、针铁矿),而中下部以高岭石等黏土矿物为主。半风化层除了包含蒙脱石等黏土矿物,还包括铁钛氧化物及辉石等硅酸盐矿物或相关蚀变矿物。风化壳样品的Sc含量为21×10^(–6)~304×10^(–6),富集程度最高可达相应基岩的3倍以上。其中,钪含量最高的样品主要分布在铁氧化物最富集的全风化层上部,其钪含量多数超过100×10^(–6)。风化壳钪含量与红土化指数(IOL)呈明显的正相关性,表明红土化过程对风化壳钪的富集有显著影响。初步研究认为钪在风化壳红土化过程中经历了活化-迁移-沉淀的多阶段富集过程:1)风化早期钪以类质同象替换的形式赋存在蒙脱石等黏土矿物中;2)风化后期磁铁矿和蒙脱石溶解,钪赋存在以铁(氢)氧化物为主的矿物中,并达到最高程度的富集(Sc>100×10^(–6));3)风化晚期铁(氢)氧化物溶解,一部分钪向下迁移到特定层位。兰排镁铁-超镁铁质岩体富钪风化壳的发现弥补了我国高品位风化壳型钪矿床的空白,丰富了成矿母岩的类型,为华南早古生代成矿作用的理论研究和战略性矿产的找矿勘查提供了一个新的方向。

已在云南4个地点发现晚中新世古猿化石:开远小龙潭,保山羊邑,禄丰石灰坝,元谋小河、竹棚、雷老。石灰坝和元谋是欧亚大陆发现古猿化石最丰富的地点,这些古猿蕴涵着重建晚新生代古猿进化史、生物地理和古生物学的重要信息。本文侧重介绍云南古猿的分类和命名,并对其系统关系和生物地理作初步分析。通过古猿化石形态模式及其变异程度的观察,初步认为:各个地点古猿化石分别代表了一个具有性二型的单一种。暂时认为禄丰石灰坝、开远小龙潭和元谋的古猿化石分别属于一个属内的两个种,其有效学名分别为Lufengpithecuslufen gensis(石灰坝标本)和L keiyuanensis(小龙潭和元谋标本)。从系统学观点看,有证据显示禄丰古猿属既为代表猩猩和人亚科共同姐妹单元原始的人科,也是代表猩猩亚科的原始姊妹单元,我们更趋向于赞同后一选择,但承认还需要通过进一步的综合对比研究来证实。迄今云南发现的古猿化石对研究人猿超科的进化历史提供独特的前景:晚中新世～上新世(8MaBP 2MaBP)时期,当人猿超科在欧亚大陆其它地区都已灭绝时,它们却连续地在云南出现。这表明中国南方或东南亚地区是人猿超科(包括猩猩和长臂猿的祖先)的一个重要的避难所。青藏高原的隆升及其对区域环境的影响,对古猿所造成的生态和地理隔离,可能是古猿?

Ther. is incr.asing r.cognition that some nanomater.als may pose a r.sk to human health and the envir.nment. Mor.over. the industr.al use of the novel engineer.d nanomater.als （ENMs） incr.ases at a higher.r.te than data gener.tion for.hazar. assessment; consequently, many of them r.main untested. The lar.e number.of nanomater.als and their.var.ants （e.g., differ.nt sizes and coatings） r.quir.ng testing and the ethical pr.ssur. towar.s nonanimal testing means that in a fir.t instance, expensive animal bioassays ar. pr.cluded, and the use of（quantitative） str.ctur.-activity r.lationships （（Q）SAr.） models as an alter. native sour.e of （scr.ening） hazar. infor.ation should be explor.d. （Q）SAr.modelling can be applied to contr.bute towar.s filling impor.ant knowledge gaps by making best use of existing data, pr.or.tizing the physicochemical par.meter. dr.ving toxicity, and pr.viding pr.ctical solutions for.the r.sk assessment pr.blems caused by the diver.ity of ENMs. This paper.cover. the cor. components r.quir.d for.successful application of （Q）SAr.methods to ENM toxicity pr.diction, summar.zes the published nano-（Q）SAr.studies, and outlines the challenges ahead for.nano-（Q）SAr.modelling. It pr.vides a cr.tical r.view of （1） the pr.sent availability of ENM char.cter.zation/toxicity data, （2） the char.cter.zation of nanostr.ctur.s that meet the r.quir.ments for.（Q）SAr.analysis, （3） published nano-（Q）SAr.studies and their.limitations, （4） in silico tools for.（Q）SAr.scr.ening of nanotoxicity, and （5） pr.spective dir.ctions for.the development of nano-（Q）SAr.models.

How Gr.vitational Effects on the Quantum Vacuum Might Explain Dar. Ener.y and Dar. Matter.Obser.ations

引用

Jour.al of Moder. Physics 2023年第6期14卷 833-838页

作者： Eugene terry Tatum Independent r.sear.her Bowling Green USA

Following a br.ef r.view of the “black hole dar. ener.y r.diation” and “gr.vitized vacuum” r.fer.nces, a novel theor. of how gr.vity might affect the quantum vacuum is pr.posed. This over.r.hing theor. pr.poses that the gr.vitational field of a sufficiently concentr.ted collection of matter.and/or.ener.y upr.gulates the vir.ual par.icle activity of the adjacent quantum vacuum, thus its ener.y density and lensing capacity. In contr.st to gener.l r.lativity, the par.icle and wave duality of quantum physics is necessar. for.under.tanding quantum vacuum gr.vitational effects. Ver. r.cent suppor.ing and pending obser.ational studies ar. discussed, including the ingenious and extr.mely sensitive vacuum scale to be deployed for.the Ar.himedes Exper.ment. Suppor. or.falsification of this pr.posal may be imminent.

How Dar. Ener.y Might Be Pr.duced by Black Holes

引用

Jour.al of Moder. Physics 2023年第5期14卷 573-582页

作者： Eugene terry Tatum Independent r.sear.her Bowling Green KY USA

If confir.ed, the new galactic obser.ations in suppor. of r.pidly gr.wing super.assive black holes in association with their.pr.duction of dar. ener.y may pr.vide for.a quantum leap for.ar. in our.under.tanding of black holes, dar. ener.y, and univer.al expansion. The pr.mar. implication of these obser.ations is that gr.wth of black holes may well be coupled with univer.al expansion (“cosmological coupling”). Study of the Flat Space Cosmology (FSC) model, in conjunction with these new obser.ations, suggests a novel mechanism of “black hole dar. ener.y r.diation”. This br.ef note gives a r.tionale for.how the high gr.vitational ener.y density vacuum within or.adjacent to a black hole hor.zon could be sufficiently ener.etic to pull entangled pair. of positive matter.ener.y par.icles and negative dar. ener.y “par.icles” of equal magnitude out of the hor.zon vacuum and send them off in opposite dir.ctions (i.e., gr.vitationally-attr.ctive matter.inwar. and gr.vitationally-r.pelling dar. ener.y outwar.). One effect would be that a black hole can r.pidly gr.w in mass-ener.y without mer.er. or.the usual accr.tion of pr.-existing matter. A second effect would be continual pr.duction of dar. ener.y within the cosmic vacuum, fueling a continuous and finely-tuned light-speed expansion of the univer.e.

r.lativity Isofr.mes—A Useful and Potentially Unifying Conceptual Fr.mewor.

引用

Jour.al of Moder. Physics 2021年第6期12卷 731-738页

作者： Eugene terry Tatum Independent r.sear.her Bowling Green KY USA

This br.ef note intr.duces the conceptual fr.mewor. of special and gener.l r.lativity isoclocks and isofr.mes. Isoclocks and isofr.mes, as defined her.in, can be used to cr.ate geometr.cal maps of space and time (“space-time”) with and without matter.embedded. They ar. useful for.having a mental pictur. of space-time r.lationships without having to pictur. 4-dimensional manifolds, which ver. few students and scientists ar. able to do. With the aid of the optical lensing definition of cur.atur. as inver.e r.dius, a new gr.vitational for.e equation is der.ved, which also incor.or.tes Einstein’s mass/ener.y r.lation in the mx ter.. Thus, one may see how it is that gr.vitational for.e cor.elates with its time-embedded cur.atur.-squar.d (Cx2) space in a mor. accur.te for.ulation than could be envisioned by Newton. This becomes mor. appar.nt in high gamma fields, such as found near.a black hole hor.zon. It is hoped that pr.bability theor.es, such as quantum field theor.es in cur.ed space-time, might be adaptable to the gener.l r.lativity isofr.me concept intr.duced her.in.
