SAFOD: 2004 sample analysis workshop

地球望远镜SAFOD下的圣安德烈亚斯断层钻探已于今年夏天(2004年)开始，将采集地质样品，这些样品为研究发震断层岩石和断层力学提供了无与伦比的机会，并将断层过程与地震过程联系起来。我们提议举办一个为期两天的小型研讨会，以协调不同科学团队对将在SAFOD钻井的不同阶段获得的岩心和岩屑样本的研究工作。一个小组将于2004年10月8日至9日在加利福尼亚州的帕索罗伯斯开会，讨论研究的优先事项和努力，并参观附近的钻探地点帕克菲尔德，那里暂时储存了样品。研讨会召集人是Jim Evans(犹他州)、Teng-Fong Wong(石溪)和Ben van der Pluijm(密歇根州)。该讲习班将有助于协调各小组的研究工作，找出我们表征研究中的任何差距，并开始制定战略，将岩石表征工作与SAFOD的其他结果相结合，包括流体和气体测量、钻孔地球物理测量、地震监测和地应力测量。

Drilling of the San Andreas Fault under Earthscope's SAFOD has started this summer (2004)and will recover geologic samples that offer unrivaled opportunity to study seismogenicfault rocks and fault mechanics, and relate fault processes to the seismic processes. Wepropose a two-day mini-workshop to coordinate the research efforts by various scientistteams on core and cuttings samples that will be obtained during the various stages ofSAFOD drilling. A small group will convene in Paso Robles, CA on October 8-9, 2004 todiscuss research priorities and efforts, as well as make a visit to the nearby drill siteat Parkfield where samples are temporarily stored. The workshop conveners are Jim Evans(Utah State), Teng-fong Wong (Stony Brook) and Ben van der Pluijm (Michigan). Thisworkshop will help coordinate research efforts of various groups, identify any gaps in ourcharacterization studies, and begin to develop strategies for integrating the rockcharacterization efforts with other results from SAFOD, including fluid and gasmeasurements, borehole geophysical measurements, seismic monitoring, and in-situ stressmeasurements.
