Cambrian/Ordovician boundary as a milestone in the sedimentation history of the southern Siberian craton: Evidence from U-Pb dating of detrital zircons by Dmitrii P. Gladkochub, Zinaida L. Motova, Tatiana V. Donskaya, Valentin B. Khubanov, Alexander V. Sizov

“…The composition of lithic fragments in these clastic sediments, including mafic and felsic volcanics and granitoids, along with the correlation of major element ratios and the values of trace-element ratios point to predominant igneous (mainly felsic) rocks in the provenance. The U-Pb ages of detrital zircons from the sampled Upper Lena Fm. sandstones are mostly Early Paleozoic (∼500 Ma), with very few Archean-Paleoproterozoic determinations and quite many Neoproterozoic zircons. …”

Historical analysis of rainfall-triggered rockfalls: the case study of the disaster of the ancient hydrothermal Sclafani Spa (Madonie Mts, northern-central Sicily, Italy) in 1851 by A. Contino, A. Contino, P. Bova, G. Esposito, G. Esposito, I. Giuffré, S. Monteleone

“…On 13 March 1851, a rainstorm brought about a severe rockfall disaster near the small town of Sclafani (Madonie Mountains, northern-central Sicily, Italy). Rocks detached from the carbonate crest of Mt Sclafani (813 m above sea level) and fell downslope, causing the collapse of the ancient hydrothermal spa (about 430 m above sea level) and burying it. …”

Evaluating heterogeneous lacustrine groundwater discharge of Hulun Lake using radium isotopes in Inner Mongolia, China by Xiaomin Gu, Mengyong Xue, Chenghui Ye, Yanwen Jiao, Yujie Han, Wenlin Wang, Xiaofei Zhang, Shaun K. Frape, Bo Liu

“…New hydrological insights for the region: The Ra isotope activities in groundwater from the fissured bedrock in the western part of the Lake are depleted relative to those from the east, underlain by the Quaternary unconsolidated sediments aquifer overlying granitic rocks. The spatial distribution of LGD under heterogeneous aquifers was revealed and groundwater discharge from fractured bedrock aquifer is the predominant source of the lake. …”
