The most recent tectonic structures of the central-eastern Internal Zones of the Betic Cordillera (from 3.1ºW to 1.7ºW and to the south of 37.525ºN) include fault and folds developed from the Late Miocene onwards, which are related to N-S/NW-SE directed continental collision and moderate thickening of a crust that is relatively hot at depth. In this setting, E-W to WSW-ENE folds, with locally associated E-W transpressive right-lateral and reverse faults, favoured the emersion of the northern Alborán basin palaeomargin and the progressive intramontane basin disconnection. The NNE-SSW to NE-SW trending regional left-lateral Palomares and Carboneras fault zones are dominant structures in the easternmost part of the cordillera. In addition, NW-SE to WNW-ESE trending normal and oblique-slip normal faults are widespread. The collision is still active and continues to drive active folds and faults, some probably being the likely source of moderate-sized earthquakes. The Campo de Dalías and surrounding sectors, deformed by active ENE-WSW folds and NW-SE to WNW-ESE oblique-slip normal faults, are probably the sites with the largest FRQFHQWUDWLRQ RI VLJQL¿FDQW HDUWKTXDNHV GXULQJ UHFHQW \HDUV 0RGHUDWHPDJQLWXGH HDUWKTXDNHV 0Z WR KDYH RFFXUUHG WKHUH at fairly regular intervals, in 1804, 1910, and 1994. Toward the east, NW-SE trending normal faults extending from Almería to the Tabernas basin deform the Quaternary rocks with associated moderate seismicity (the 2002 Gergal Mw 4.7 earthquake, and possibly the 1894 Nacimiento earthquake, felt with intensity VII). In the Sorbas-Vera basin, the Palomares fault zone is also responsible for moderate-sized earthquakes (1518 Vera earthquake). In the Almanzora corridor, NW-SE to WNW-ESE trending Lúcar-Somontín faults also could be considered one of the possible source of moderate-magnitude seismicity (1932 Lúcar, Mw 4.8 earthquake felt ISSN (print): 1698-6180.

“…The composition of oceanic island basalts (OIB) and the normalizing values are from Sun and McDonough (1989) both the cores and rims of the clinopyroxenes from the Luotuogou samples are characterized by strong depletions in LREEs (Fig. 5), which are also inconsistent with crustal contamination (Duggen et al, 2008). These lines of evidence therefore argue against crustal contamination as a controlling factor for the elemental and isotopic composition of the Luotuogou gabbros which must reflect characteristics of the mantle source.…”
