Be cosmogenic dating
Terrestrial cosmogenic nuclides are produced by interactions between secondary cosmic rays and near surface rocks.Our research interests cover a wide spectrum of earth scientific disciplines and include timing of ice ages, subglacial erosion rates, uplift rates of Pleistocene terraces, and a better understanding of the production systematics of cosmogenic nuclides.Therefore, 18.0 ± 1.1 ka should be regarded as a minimum age with a probable true age much closer to the local-LGM values (~20 ka) as observed in the surrounding mountains.Biggs looked exactly like Third Master Fan, drunk as he accepted cosmogenic dating glaciers loaf. There are other known asteroids that do not orbit within the Main Belt (such as various near Earth objects or NEOs), and some of these also could be sources of meteorites.The most prevalent meteorites found on Earth contain small, partly glassy spheres called chondrules, and such rocks are termed chondrites (of at least 14 different types).

The piedmont glaciers originated from the Geyikda g ice cap (~40 km 2), situated between 23 m above sea level (a.s.l.) (Central Tauride Mountains of Turkey), and deeply carved the north-facing hillslopes before reaching the Namaras Valley (2000e2050 m a.s.l).The hummocky moraines resulted from in-situ deposition of stagnant glacier ice where debris cover was heterogeneously distributed on the glacier surface.The oldest deglaciation occurred in the Namaras Valley at 18.0 ± 1.1 ka (ka: thousand years ago) towards the end of the Last Glacial Maximum (LGM) and is recorded entirely by hummocky moraines.We speculate that hummocky moraine forming processes with cycles of relief inversion gave rise to boulder apparent ages up to a few thousand years younger in our study area.
