“…Alteration to montmorillonite occurs at temperatures 100-120 °C (Henley and Ellis, 1983). Low temperature hydrothermal dioctahedral smectites has been referred close to the surface of the geothermal fields (Cole, 1988;Mizoto, 1998;Mas, 2003;). On the other hand, synthesis of dioctahedral smectite is achieved under elevated temperatures (Tomita, 1993).…”

Hisaralan jeotermal sahası Simav Grabeni ile İzmir-Balıkesir Transfer Zonu (IBTZ)'nin kesişim yerinde bulunmaktadır. Alan Erken Miyosen dasidik ve riyolitik volkaniklerden oluşmaktadır. Kil mineralojisi güncel ve fosil hidrotermal alterasyonu belirlemek için araştırılmıştır. HS-2 sondaj kuyusu ve yüzey örneklerinin mineralojisi XRD, SEM ve optik mikroskop ile çalışılmıştır. R2 IS ve simektit yüzeye yakın kesimlerde baskınken saf illit ve R3 IS jeotermal alanın derin kesimlerdeki baskın kil mineralleridir. Fosil hidrotermal sistem iki evrede gerçekleşmiştir. İlk olarak, piropilitik alterasyonu işaret eden Fe-zengin klorit, kalsit ve pirit oluşmuştur. Bunu takip eden, saf illit ve illitçe zengin IS piropilitik alterasyonu üzerlemiştir. Rb/Sr izotop verileri illitik minerallerin (illit ve/veya IS) Erken Miyosen volkanizması ile yaş ve köken bakımında eş olduğunu göstermektedir. Diğer taraftan, aktif hidrotermal alterasyonun dioktahedral simektit çökelttiği varsayılmaktadır. Element aktiviteleri termal suların 100 ⁰C ve altında simektit ile dengede olduğunu göstermektedir. Çatlaklarda ve önceki alterasyon ürünlerinin yüzeyinde sıvamalar şeklinde bulunan halloysit geç evre oluşumudur. Killere ait O ve H izotop verileri simektit mineralinin aktif jeotermal sisteme ait olduğunu ve halloysitin meteorik kökenli düşük sıcaklıklı sulardan çökeldiğine işaret eder. Düşük sıcaklıklı jeotermal sistemler simektit çökeltmektedir ve fay zonlarının kesişim yerleri Hisaralan ve çevresindeki güncel jeotermal alanlar için karakteristiktir.

“…Another typical weathering characteristic of an igneous island arc terrane is the absence of illite or illite-smectite mixed layers. Hydrothermal illite and illite-smectite mixed-layers may form in the geothermal fields related to the volcanic activity, as documented on the islands of Guadeloupe to Grenada (Mas et al, 2003(Mas et al, , 2006Murray et al, 2018;Parra et al, 1986). However, the spatial extension of geothermal areas is too limited to exert a significant contribution to clay material accumulated in marine sediments.…”

“…Randomly ordered smectite/illite is replaced by ordered (R ¼ 1, 50-70% illite) smectite/illite at 120-1808C. Above 1808C smectite/illite mixed layered clays are dominated by illite, at concentrations > 70% (Mas et al, 2003).…”

Subglacial Hydrothermal Alteration Minerals in Jökulhlaup Deposits of Southern Iceland, with Implications for Detecting Past or Present Habitable Environments on Mars

Jökulhlaups are terrestrial catastrophic outfloods, often triggered by subglacial volcanic eruptions. Similar volcano-ice interactions were likely important on Mars where magma/lava may have interacted with the planet's cryosphere to produce catastrophic floods. As a potential analogue to sediments deposited during martian floods, the Holocene sandurs of Iceland are dominated by basaltic clasts derived from the subglacial environment and deposited during jökulhlaups. Palagonite tuffs and breccias, present within the deposits, represent the primary alteration lithology. The surface abundance of palagonite on the sandurs is 1-20%. X-ray diffraction (XRD) analysis of palagonite breccias confirms a mineral assemblage of zeolites, smectites, low-quartz, and kaolinite. Oriented powder X-ray diffractograms (< 2 microm fraction) for palagonite breccia clasts and coatings reveal randomly ordered smectite, mixed layer smectite/illite, zeolites, and quartz. Visible light-near infrared (VNIR) and shortwave infrared (SWIR) lab spectroscopic data of the same palagonite samples show H2O/OH(-) absorptions associated with clays and zeolites. SWIR spectra derived from Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) images of the sandurs reveal Al-OH(-) and Si-OH(-) absorption features. The identified alteration mineral assemblage is consistent with low temperature (100-140 degrees C) hydrothermal alteration of basaltic material within the subglacial environment. These results suggest that potential martian analog sites that contain a similar suite of hydrated minerals may be indicative of past hydrothermal activity and locations where past habitable environments for microbial life may be found.
