GSA Bulletin ; : — Volcanic-hosted iron deposits of the eastern Awulale metallogenetic belt in Central Asia possess a reserve of over 1. Skarns are widespread in these deposits and closely associated with iron mineralization. The ages of these skarns are unclear, and their genesis remains debated, preventing further investigation into their metallogenic processes. We focused on garnets in nine ore-bearing skarns from three large-scale iron deposits Chagangnuoer, Dunde, and Beizhan in the eastern Awulale belt. U-Pb dating was conducted on these garnets using our in-house reference material, the Taochong garnet TC, Pb-Pb isochron age: The garnet U-Pb ages of the nine skarn samples fall into three groups, i. The first and second episodes of skarns formed as a result of contact metasomatism between coeval volcanic rocks and limestone, and they have economically important iron mineralization. The third was likely caused by a local postcollision granitic intrusion, but its metallogenic potential deserves further assessment. Shibboleth Sign In.

Place your domains in a reverse auction for hours. You will need to pay the transfer fee with a deposit fee sufficient to cover the transfer fee. If you dont complete the sale within 7 days you will lose their deposit and the liquidation auction can resume. Abuse cases are recorded within Epik’s customer service system, and you should receive a confirmation email with a ticket number. Epik makes a concerted effort to respond to every abuse report within 24 hours and to take prompt action, as appropriate, to stop illegal or nefarious activity.

Metrics details. The evolution of male pregnancy is the most distinctive characteristic of syngnathids, and their specialized life history traits make syngnathid species excellent model species for many issues in biological evolution. However, the origin of syngnathids and the evolutionary divergence time of different syngnathid species remain poorly resolved. Comprehensive phylogenetic studies of the Syngnathidae will provide critical evidence to elucidate their origin, evolution, and dispersal patterns.
We sequenced the mitochondrial genomes of eight syngnathid species in this study, and the estimated divergence times suggested that syngnathids diverged from other teleosts approximately The two most frequently used codons in syngnathid fishes were different from those in other teleosts, and a greater proportion of the mitochondrial simple sequence repeats SSRs were distributed in non-coding sequences in syngnathids compared with other teleosts.
Our study indicated that syngnathid fishes experienced an adaptive radiation process during the early explosion of species. The specialized brood pouch provides protection and carries out gas exchange, osmoregulation, and limited nutrient provisioning for the developing embryos [ 4 , 5 ]. In addition, members of the family Syngnathidae exhibit other unique features such as an extended body covered with an armor of bony plates instead of scales, elongated snout, and fused jaws.
Live interview elements were interspersed with pre-recorded segments that generally veered towards light, enjoyable fluff: CL bonding with L. But in one particularly vulnerable part, when she talked about her four-year struggle to succeed in America, her eyes filled with tears. People want to help but they don’t know how to help. Thanks to global fans and her long-running affiliations with Western fashion designers like Jeremy Scott, that recognition had started to spread. But since the release of her debut U.

The second half of twentieth century has seen some of the most important developments in chemical analysis in geology and geochemistry. Based on the well-known physical rules that drive the behavior of particles and rays, recent technological advances have created opportunities for new developments based on microbeams : Electrons, ions, protons, neutrons, X-rays, IR to UV lights including laser. We encourage contributions that highlight new protocols and technical improvements, as well as original works based on the combination of different techniques.
Download all presentations MB. The earliest known physical records of Mars and Earth lie in microscopic grains of zirconium-rich geochronology minerals such as zircon and baddeleyite. The reconstruction of the pressure and temperature histories of these phases is one of the few ways in which we can bracket the onset of conditions permissive of microbiota survival, and requires an integration of several nanoscale measurement techniques.
The approach is to spatially correlate measurements of the chemical and orientation microstructure of individual grains in order to characterize thermal, shock and diffusion history and better interpret U-Pb geochronology data. Also revealed are proxies for high temperature metamorphism such as nanoclusters of Pb and trace elements and nanoveins of impact melt as well as trace elements introduced through subsequent lower-temperature hydrothermal metamorphism.

Women engaging in compensated dating is one of the at risk group of HIV infection due to multiple sexual partnerships and risky sexual practices. The present study examined the prevalence of HIV testing behavior and intention, and identified factors associated with HIV testing intention among women engaging in compensated dating in Hong Kong.
Factors from the Theory of Planned Behaviors and the role of various types of barriers to HIV testing were also explored. An anonymous, cross-sectional survey was conducted online. Target participants were women who have engaged in compensated dating and provided sex services to clients. Participants were recruited via three sources, including i online outreaching, ii referral made by NGOs, and iii referral made by participants.

A ‘read’ is counted each time someone views a publication summary such as the title, abstract, and list of authors , clicks on a figure, or views or downloads the full-text. These identify the institution that issued the card to the card holder. The Bank Identification Number, also known as the credit card bin can tell you the name of the bank that issued the card, the type of card like Debit or Credit, brand of card Visa, MasterCard and level of card like Electron, Classic and Gold.

The occurrence timing of large earthquakes is believed to be correlated positively with the exposure duration of bedrock fault surfaces. Accordingly, cosmogenic nuclides concentration determined for the bedrock footwall can offer their times, ages, and slip over long time. In general, multiple sites of fault scarps along one or even more faults are selected to carry out cosmogenic nuclide dating in an attempt to derive the temporal and spatial pattern of fault activity.

Patients and Methods. Physicians and nurses were selected to be trained in international centers, and a transplantation unit was developed at Luis Calvo Mackenna Hospital in Santiago. Between October and December , 59 patients received transplants. Of these, 42 were from HLA-matched family members and 11 were autologous.
