The paper introduces a number of new research results on the characteristics of lead - zinc ores in Phia Dam - Khuoi Man areas based on the application of traditional geological methods, combining the method of researching material composition and method statistical maths. In the study area, there are two forms of ore bodies with characteristics described as below: the first form consists of ore bodies developed along the stratabound bedding surface, are mainly distributed in either anticlinal structures (i.e. Phia Dam region) or cuesta (i.e. Khuoi Man region) and the second form consists of ore bodies in lodes, filled in cracks or zones of fracture along the northwest – southeast faults. Primary ore minerals are mainly galena, sphalerite, pyrite, chalcopyrite, etc. and gangue minerals are calcite, dolomite, and quartz. Ore structures are nests, veins, disseminated veins, banded, speckled, or sometimes breccia - like ones. The relevant and controlling factors of lead-zinc mineralization in Phia Dam - Khuoi Man region are the northwest - southeast fault system and the lithostratigraphy. Ores are of either mesothermal or epithermal deposits (temperatures varies from 162 to 308 degrees Celcius), with a specific symbiotic combination of quartz - sphalerite - galena - chancopyrite.

Simple Language

Starting with introduction to the geologic environment, this book elaborates the theory, cause, and current situation about the highway damages in the Wenchuan Earthquake Stricken Area in simple language on the basis of a great deal of full and accurate investigation data about the Wenchuan Earthquake and post-earthquake geological disasters. These results provide valuable technical support for the reconstruction of post-earthquake highways and prevention of post-earthquake geological disasters. This book, the pictures and their accompanying text are both excellent. This book is divided into fourteen chapters, covering geological disaster review, surface rupture zone and liquefaction, collapses and landslide and post-earthquake secondary debris flow, as well as a large number of precious affected highway examples.

During the M s 8.0 Wenchuan Earthquake of May 12, 2008, three distinct faults in the Longmen Shan along the eastern margin of the Tibetan Plateau ruptured. We have carried out detailed field geological mapping on these faults (the Yingxiu-Beichuan, the Pengxian-Guanxian, and the Xiaoyudong Faults), as well as the minor Leigu Fault, using GPS and total station surveys. The surface rupture of the Wenchuan Earthquake consists of two margin-parallel thrust faults linked by the Xiaoyudong tear fault. By comparing the features of the surface rupture of the faults, the spatial relationships between the different surface ruptures can be determined. It is clear that the margin-parallel thrust faults are linked at depth, forming an imbricated thrust linked by a tear fault.

Abstract Background While there have been published reports detailing technical challenges of incorporating genetic test results into the electronic health record (EHR) with proposed solutions, less has been published about unanticipated sociotechnological or practical communication challenges involved in this process. Objectives This study was aimed to describe unanticipated issues that arose returning genetic research results through the EHR as part of the National Human Genome Research Institute (NHGRI)-funded electronic Medical Records and Genomics (eMERGE) 3 consortium, and provide lessons learned for future implementations Methods We sequenced 3,000 participants on a 109-gene panel and returned genetic results initially in person and/or by letter, with a later release directly into the EHR and patient portal. Results When results were returned through the EHR, multiple participants expressed confusion and contacted the health system, resulting in our institution temporarily freezing our return of research results. Discussion We determined the likely causes of this issue to be (1) the delay between enrollment and results return, (2) inability to personalize mass e-mail messages announcing new research test results in the EHR, (3) limited space for description of test results in the EHR, and (4) the requirement to list an ordering physician for research results in the EHR. For future return of results, we propose sending preparatory e-mails to participants, including screenshots of how they can expect to see their results presented in the EHR portal. Conclusion We hope our lessons learned can provide helpful guidance to other sites implementing research genetic results into the EHR and can encourage EHR developers to incorporate greater flexibility in the future.
