Figure 43. Early Jurassic (Hettangian through Pliensbachian - 208 to 193 Ma) stage of metallogenic-tectonic model. Refer to text for explanation of metallogenic-tectonic events, to tables 3 and 4 for descriptions metallogenic belts and significant deposits, and lo figure 18 for explanation of abbreviations, symbols, and patterns. Adapted fiom Nokleberg and others (1997b, 1998.2000). Specific Events for Early Jurassic (1) The Monakin continental-margin arc, consisting of the Monakin volcanic-plutonic belt (mo) and the Umlekan continental- margin arc, consisting of the Umlekan-Ogodzhin volcanic-plutonic belt (uo) and associated units, commenced adivity. Associated with this arc was oblique (sinstral) subduction of part of the Ancestral Pacific Ocean plate to form the Samarka (SMA), Khabarovsk (KB), and Badzhal (BD) terranes. (2) The continental-margin arc Uda arc (consisting of the Uda volcanic-plutonic belt (ud) and Uda-Zeya sedimentary basin (uz) continued to fonn. Associated with the arc was subduction and sinistral transpression of part of the Mongol-Okhotsk Ocean plate to form the Turkuringra-Dzhagdinski (TD), Ulban (UL), and Galam (GL) terranes. Subduction and sinistral transpression occurred along the Mongol-Okhotsk suture (MO). (3) The extensive Kony-Murgal island arc (Kony-Mwgal terrane (KM)) continued to form as an offshore extension sf the Uda arc. Associated with the arc was subduction of part of the Ancestral Pacific Ocean plate to fonn the Tdovskiy (TL) and Penzhina-Anadyr (PA) terranes. Inboard of the Kony-Mwgal island arc (KM) were the Okhotsk (OK), Avekova (AK), and Omolon (OM) cratond temes which were previously rifted from the North Asian Craton (NSC), and the Viliga WL) passive continental-margin Crranes which was previously rifted from the North Asian Craton Margin O\ISV). Behind the arc were 6agments of prior Devonian to Pennsylvanian island-arc terranes, including the Beryozovka turbidite-basin (BE), and Oloy (OL), and Yarakvaam (YA) i.sland-arc terranes.
