描述----------Description----------
Data recording the spatial locations of gold deposits and associated geological features in the Murchison area of Western Australia. Extracted from a large scale (1:500,000) study of the Murchison area by the Geological Survey of Western Australia (Watkins and Hickman, 1990). The features recorded are
在西澳大利亚默奇森区域的金矿和相关的地质特征的空间位置数据记录。摘录从大规模（1:50万）研究的默奇森区西澳大利亚地质调查局（金丝和Hickman，1990）。记录
the locations of gold deposits;
金矿床的位置;
the locations of geological faults;
地质断层的位置;
the region that contains greenstone bedrock.
区域包含绿基岩。
The study region is contained in a 330 * 400 kilometre rectangle. At this scale, gold deposits are points, i.e. their spatial extent is negligible. Gold deposits in this region occur only in greenstone bedrock. Geological faults can be observed reliably only within the same region. However, some faults have been extrapolated (by geological “interpretation”) outside the greenstone boundary from information observed in the greenstone region.
研究区域包含在330 * 400公里矩形。在这个规模，金矿床点，即它们的空间范围是可以忽略不计。在这一区域的金矿只发生在绿基石。可以观察到可靠的只有同一区域内的地质断层。然而，一些故障推断（地质“解释”）外绿的边界在绿区观察到的信息。
These data were analysed by Foxall and Baddeley (2002) and Brown et al (2002); see also Groves et al (2000), Knox-Robinson and Groves (1997). The main aim is to predict the intensity of the point pattern of gold deposits from the more easily observable fault pattern.
这些数据进行了分析Foxall和巴德利（2002）和Brown等人（2002年）; Groves等人（2000年），诺克斯 - 罗宾逊和格罗夫斯（1997）。的主要目的是预测的点图案的金矿床的强度，更容易观察到的故障模式。
