西澳大利亚州特尔弗矿

Landsat 9’s Operational Land Imager-2 captured this image of the open pits and ponds of Telfer Mine and the surrounding rust-colored soil on Dec. 15, 2023. The soils have a reddish tint from the iron oxides that have accumulated from millions of years of weathering. This part of Western Australia is known for being rich in natural resources, including petroleum, iron ore, copper, and certain precious metals. Beneath the soils, veins of gold and silver run through sedimentary rocks, such as quartz sandstone and siltstone, that formed about 600 million years ago, when much of Australia was under water.

陆地资源卫星9号的二代陆地成像仪于2023年12月15日拍摄了特尔弗矿露天矿坑和池塘以及周围铁锈色土壤的图像。土壤因数百万年风化积累的氧化铁而呈淡红色。西澳大利亚的这一地区以丰富的自然资源而闻名，包括石油、铁矿石、铜和某些贵金属。在土壤之下，金和银的矿脉贯穿石英砂岩和粉砂岩等沉积岩，这些沉积岩形成于大约6亿年前，当时澳大利亚大部分地区都在水下。
