The Lake District Ordovician Mafic Plutonic Suite (OMPS) and Ordovician Minor Intrusion Suite (OMIS) also formed in this period (Fig. 1). Subsequent waning in volcanism and regional subsidence led to a marine transgression marked by an unconformable boundary and the Windermere Supergroup (WSG) –...
which is basically consistent with the trend of climate warming. The north of China has been suffering from drought since the 1980s. In 2010 the southwestern region of the country experienced a period of unusual droughts that lasted a long time and had a great impact. Also, the area in the...
Strata within the Zhangjiakou area mainly comprise Archean and Paleoproterozoic metamorphic series, Paleozoic–Mesozoic sedimentary series, and Jurassic–Cretaceous volcanic–sedimentary series. Among them, the Mesoarchean Guzuizi Formation is chiefly distributed south of the Shangyi–Chongli–Chicheng Fault,...
the Swiss border, before and after 1829, Browell here found that there are obvious characteristics of strata, so named mountains, if in 1820 the British first named Smith, now is certainly not the name of the Jurassic, because he was in the UK face research AMMONOID exactly this period. ...
the east. The timing of these tectonic events is controversial, but tiltedMiocenelava flowswest of the crest, and faultedPliocenebasaltflows in the ranges east of the Sierra Nevada indicate that much of the early tectonic activity started before theQuaternary Period, although faulting continues today...
The ALTENBERG DE BERGHEIM is located in the heart of the geological faults fields of RIBEAUVILLE where hard limestone and Jurassic Lias marls meet each other. These abundant formations in fossils form a poor clay-limestone soil, red (ferruginous), and rich in rock limestone, where the vines mu...
