We review new advances in volcano–ice interactions on Mars and focus additional attention on (1) recent analyses of the mechanisms of penetration of the cryosphere by dikes and sills; (2) documentation of the glacial origin of huge fan-shaped deposits on the northwest margins of the Tharis Montes and evidence for abundant volcano–ice interactions during the later Amazonian period of volcanic ed...

Heterogeneous pyritaceous-polymetallic and copper-zinc-pyrrhotine deposits on the South slope of the Greater Caucasus are located in the Lower-Middle Jurassic terrigenous sediments. They were formed under a wide variation of physico-chemical parameters of mineral formation and are characterized by specific mineralogical-geochemical peculiarities. Ore-formation occurred in three stages. In the f...

background: there is no conclusive evidence on the effect of orthodontic force application on dental pulp tissue. the aim of this study was to compare early and delayed histological effects of intrusive forces on dental pulp of adolescents and adults. materials and methods: patients referred to the department of orthodontics of mashhad university of medical sciences participated in this study. ...

Introduction: The GRAIL (Gravity Recovery and Interior Laboratory [1]) mission has enabled unprecedented views of the lunar crust and interior structure. Indeed, the data solutions now resolve gravity anomalies arising from lateral heterogeneities within the crust globally at scales < 10 km[2,3]. Intrusive magmatic features such as dikes and sills are predicted to be prevalent within the lunar ...
