Durango volcanic field

{{short description|Volcanic field in Durango State, Mexico}} thumb|La Breña-El Jagüey maar complex {{coord|24.15|N|104.45|W|display=intitle|notes=<ref name="GVP" />}} '''Durango volcanic field''' is a volcanic field in north-central Mexico (Durango), east of the Sierra Madre Occidental. The field covers a surface area of {{convert|2100|km2}}.<ref name="GVP" />

The volcanic field is located in the Tepehuano terrane. Volcanism in the area was accompanied by tectonic extension.<ref name="LuhrGomez1997" /> There are around hundred cones in the field.<ref name="GVP" /> Some volcanic rocks have been affected by faulting; buried faults are also found.<ref name="LuhrGomez1997" /> The San Luis-Tepehuanes fault system is associated with the field.<ref name="Nieto-SamaniegoAlaniz-Álvarez2007" /> The whole field is covered by lavas, which are about {{convert|10|m}} thick and reach a total volume of {{convert|20|km3}}.<ref name="LuhrKimberly2006" /> Magma ascent has been controlled by northwest-trending faults.<ref name="Aranda-GómezLuhr2007" /> Volcanism in the wider territory was related to the subduction of the Farallon plate until 29 mya. Later tectonic changes caused a start of more alkaline volcanism.<ref name="ArandaLuhr1992" />

The volcanoes have erupted basanite.<ref name="GVP" /> The main components of the rocks at La Breña-El Jagüey are clinopyroxene, ilmenite, olivine, plagioclase and titanomagnetite, with rocks sporting variable textures. The participation of water in the formation process of these magmas is debatable; the rocks may have been influenced by sediments from the uppermost part of the subducting Farallon slab.<ref name="PierLuhr1992" /> These rocks are of mafic intraplate geochemistry.<ref name="LuhrKimberly2006" /> The rocks contain mantle xenoliths.<ref name="LassiterLuhr2001" />

The most prominent volcanic centres of the field are the La Breña-El Jagüey maars. They form intersected craters and the larger Brena crater has cinder cones within.<ref name="GVP" /> The diameter of the Brena maar is {{convert|1400|m}} and Jagüey {{convert|700|m}}, rising above a {{convert|2000|m}} high lava plain. Each maar is surrounded by a tuff ring {{convert|30|-|70|m}} high. Jaguey presently holds a permanent lake and the formation of both maars was probably influenced by groundwater. Jaguey maar likely formed first, with the Brena maar forming eruption generating surge fields. The formation of the maars has partly buried some neighbouring cinder cones.<ref name="ArandaLuhr1992" /> Other cones in the field may date back to Pliocene-Pleistocene times given their state of degradation; one K-Ar date is 0.8 mya.<ref name="Aranda-GómezLuhr2007" />

These two maars may be the most recent eruption products of the field,<ref name="GVP" /> likely of Holocene age given the unvegetated appearance of the lava flows.<ref name="ArandaLuhr1992" /> The field is an inhospitable terrain.<ref name="MathisHafner2014" />
