“…The Menderes Massif is made up of a latest Neoproterozoic-early Cambrian basement (core series) and an unconformably overlying Palaeozoic-Early Tertiary cover series ( Figure 2(b); Dürr, 1975;Koralay et al, 2012). A generalised lithostratigraphy for the basement consisting of a thick metaclastic sequence and numerous syn-to post-metamorphic basic to acidic intrusions are suggested.…”

“…The metaclastic sequence, with a minimum thickness of 10 kms, forms the oldest unit of the basement. It can be divided into two subunits; a paragneiss unit and a schist unit Dora, Candan, Kaya, Koralay, & Dürr, 2001;Koralay et al, 2012). The partly migmatized paragneiss unit, up to 8 km in thickness, occurs at the lower levels of the sequence and contains mica schist interlayers, up to 200 m in thickness.…”

“…The schists contain subordinate biotite-albite schist layers (~30%) representing former subarkosic sandstones. Based on the geochronological data, the depositional age of the protoliths of the paragneiss-schist sequence is constrained between 600 and 590 Ma, i.e., Ediacaran (Koralay et al, 2012).…”

“…Within this general tectonic framework, the Menderes Massif forms the largest crystalline basement of the Anatolides. In addition to Alpine overprint, petrological, petrographical and geochronological data indicate that the basement of the massif has experienced late Neoproterozoic poly-phase metamorphic events under granulite-, eclogite-and amphibolite-facies conditions (Candan, 1995;Candan & Dora, 1998;Candan, Dora, Dürr, & Oberhänsli, 1994;Candan et al, 2001;Oberhänsli, Candan, Dora, & Dürr, 1997;Oberhänsli, Candan, & Wilke, 2010) and was intruded by late Neoproterozoic basic and acidic magmas (Candan, 1996;Candan et al, in press;Gessner et al, 2004;Hasözbek, Akay, Erdoğan, Satır, and Siebel 2011;Hetzel & Reischmann, 1996;Koralay et al, 2011Koralay et al, , 2012Koralay et al, , 2004Loos & Reıschmann, 1999).…”

In many papers, the poly-metamorphic evolution of the Precambrian basement series of the Menderes Massif has been attributed to the Pan-African Orogeny and was related to the closure of the Mozambique Ocean during the assembly of Gondwana (Candan, Dora, & Oberhänsli et al, 2001;Candan et al, in press;Dora, Candan, Kaya, Koralay, & Akal, 2005;Koralay , 2012.…”

Late Neoproterozoic granulite facies metamorphism in the Menderes Massif, Western Anatolia/Turkey: implication for the assembly of Gondwana

The Menderes Massif is a major polymetamorphic complex in Western Turkey. The late Neoproterozoic basement consists of partially migmatized paragneisses and metapelites in association with orthogneiss intrusions. Pelitic granulite, paragneiss and orthopyroxene-bearing orthogneiss (charnockite) of the basement series form the main granulite-facies lithologies. Charnockitic metagranodiorite and metatonalite are magnesian in composition and show calc-alkalic to alkali-calcic affinities. Nd and Sr isotope systematics indicate homogeneous crustal contamination. The zircons in charnockites contain featureless overgrowth and rim textures representing metamorphic growth on magmatic cores and inherited grains. Charnockites yield crytallization age of~590 Ma for protoliths and they record granulite-facies overprint at~580 Ma. These data indicate that the Menderes Massif records late Neoproterozoic magmatic and granulite-facies metamorphic events. Furthermore, the basement rocks have been overprinted by Eocene Barrovian-type Alpine metamorphism at~42 Ma. The geochronological data and inferred latest Neoproterozoic-early Cambrian palaeogeographic setting for the Menderes Massif to the north of present-day Arabia indicate that the granulite-facies metamorphism in the Menderes Massif can be attributed to the Kuunga Orogen (600-500 Ma) causing the final amalgamation processes for northern part of the Gondwana.

Hydrogeochemical investigation of irrigation water in the vicinity of metallic ore deposits in Kiraz‐İzmir, Turkey: Understanding the crucial nexus between “geology and food safety”

The increasing drought due to climate change poses a threat to issues such as safe and accessible drinking water, food safety, and protection from diseases. The provision of water supply is vital for agricultural and livestock activities, which are commonly practiced around natural ore deposits. Examining traditional “irrigation water quality” methods alone is insufficient; investigating potentially toxic metal content in the region's waters is vital, especially around metallic ore deposits. This study focused on the Kiraz district in Turkey, known for its agricultural activities, to assess the impact of geogenic water pollution on irrigation water quality and its implications for food safety and human health. Geology determines nutrient availability, water resources, and land suitability for agriculture. Conventional irrigation water quality parameters indicate groundwater suitability for irrigation in the study area, considering Na%, sodium adsorption ratio, residual sodium carbonate, permeability index, Kelly ratio, magnesium hazard, and potential salinity. However, when examining the potential toxic metal content in the region, it was determined that the values of Al ranged from 96 to 8676 ppb, Ni values ranged from 27 to 360 ppb, and Sb concentrations varied between 9 and 53 432 ppb. Utilizing geogenically contaminated water for irrigation and its indiscriminate use in livestock, dairy, and food industries can lead to foodborne illnesses (cancer, endocrine disruptors, tuberculosis, antimony spots, thyroid tumors, goiter, neurologic and cardiovascular diseases) that endanger human health. The use of low‐quality water throughout the agricultural sector and food production chain increases food safety risks.
