lacustrine deposits
Lakebed accumulated materials
Lacustrine deposits are sediments that accumulate at the bottom of lakes—layers of silt, clay, organic matter, and minerals that settle over time.
Geologists study these deposits to reconstruct past climates and environments, since each layer preserves evidence of conditions when it formed: The lacustrine deposits revealed thousands of years of drought cycles.
