Jaguar is a remarkably pristine finely banded submarine volcanic hosted base-metals-silver deposit from the Australian Archean, ~2.7 billion years old. We will document its detailed ore and volcanic textures, gaining valuable new genetic insights from its extraordinary preservation. With an emerging mining company in regional Western Australia, we will combine forensic textural studies with advanced geochemical analysis to (1) determine the deposit origin; (2) infer the origin of other well laminated but less well preserved deposits globally; (3) apply these findings to the detection of local prospective horizons under deep cover; and (4) use the deposit features to test current models of massive sulfide formation.

美洲虎产于澳大利亚太古代，是一个非常原始的细带状海底火山贱金属银矿床，距今约27亿年。我们将记录其详细的矿石和火山结构，从其非凡的保存中获得有价值的新的成因见解。我们将与西澳大利亚地区的一家新兴矿业公司合作，将法医结构研究与先进的地球化学分析相结合，以(1)确定矿床的成因；(2)推断全球其他层状构造较好但保存较差的矿床的成因；(3)将这些发现应用于探测当地的深部潜在矿层；以及(4)利用矿床特征来测试当前的块状硫化物形成模式。
