the Orapa area in central Botswana. Early prospecting in the eastern Botswana hardveld in the late 1950s to early 1960s resulted in the recovery of a train of diamonds in the east-flowing Motloutse River, extending to the headwaters of this drainage line. De Beers concluded that the Motloutse had pr澄清 发表于 2025-3-27 08:47:53

Ivan Markovskyimates of marine influence. The main landform aspects of the two main islands (Fernando de Noronha and Trindade) are presented, showing the importance of volcanic activity at hot spots, with older events in Noronha, resulting in extensive weathering and erosion of the less resistant rocks (tuffs, scDALLY 发表于 2025-3-27 16:35:54

The wall of the subsequent Jenoy caldera is covered by glacial morphology indicating a pre-glacial (<ca. 20 ka) age. These data suggest that the location of the eruptive main单调女 发表于 2025-3-28 04:53:42
