Biological, physical and chemical characteristics of the water column of a shallow (Zmax = 9.2 m), small (surface area 3.8 km2) residential and recreational lake near Prince George, British Columbia, indicated that the system was being loaded internally with phosphorus (P) from the sediments. The abundance of P released from the fine glaciolacustrine, and organic rich sediments was resulting in...

High-resolution paleomagnetic investigations were performed on Río Valdez outcrop at the Fagnano Lake, central Isla Grande de Tierra del Fuego, southernmost South America. Our aims to develop a full-vector secular variation (PSV) record and establish chronostratigraphy for based radiocarbon dating correlation of PSV with other dated records in region.

The sandstone-hosted Beverley uranium deposit is located in terrestrial sediments in the Lake Frome basin in the North Flinders Ranges, South Australia. The deposit is 13 km from the U-rich Mesoproterozoic basement of the Mount Painter inlier, which is being uplifted 100 to 200 m above the basin by neotectonic activity that probably initiated in the early Pliocene. The mineralization was deposi...
