Interpretation of the Magma Chamber Processes with the Help ofTextural Stratigraphy of the Plagioclases (Konya-Central Anatolia)
Öz: The variations in the chemical composition and micro-texture of a mineral from the core to the rim allow the sequencing of the formationof the magma chamber processes and the interpretation of which texture might have been formed by which process. In this contribution,the textural and chemical zoning of the plagioclases, which are a significant recorder of magma chamber processes, from some enclave containing andesites (calc-alkaline) and basalts (calc-alkaline) from the Karapınar-Karacadağ Volcanic Units, were examined and theirtextural mineral stratigraphies were investigated to enlight the magma chamber processes. Plagioclases from the andesitic host-rock andtheir enclaves generally exhibit different composition from core to rim. The composition in the enclave ranges from oligoclase tolabradorite (core:An25-72), however, in the host rock it ranges from andesine to labradorite (core:An46-64). It is noteworthy that theplagioclases in the host-rock are mostly rounded, and reverse and oscillatory zoned with Anorthite, Fe, Mg, Sr, and Ba. However in theenclaves they display generally fine sieve and dusty sieve textures. The cores of the plagioclase micro-phenocrysts in calc-alkalinebasalts are andesine-labrador (An32-66) in composition. Remarkably, plagioclases in basalts show reverse and oscillatory zoning withAn, Fe, Mg, Sr, and Ba, and as well as exhibit coarse-grained sieve texture with glass and microlitic inclusions, and spongy cellulartextures. Combined with their An, Fe, Mg contents it is suggested that some of the plagioclases from the basalts may be xenocrystsrather than phenocrysts. Considering the textural and chemical properties of the plagioclases, in the formation of reverse and oscillatoryzoning in the basaltic rocks, the decompression processes in addition to the magma mixing processes (magma mixing/self-mixing) alsohave an impact on the genesis of the basalts. However, in the formation of andesitic rocks, the magma replenishment processes have akey role rather than decompression or temperature-pressure change.
Anahtar Kelime: Plajiyoklazların Dokusal Stratigrafisi ile Magma Odası Süreçlerinin Yorumlanması (Konya-Orta Anadolu)
Öz: Çekirdekten kenara bir mineralin kimyasal bileşimindeki ve mikro dokusundaki varyasyonlar, magma odası süreçlerinin oluşumununsıralanmasına ve hangi dokunun hangi süreçle oluşmuş olabileceğinin yorumlanmasına olanak tanır. Bu çalışmada, Karapınar Karacadağ Volkanik Birimleri'nden bazı anklav içeren andezit (kalk-alkalen) ve bazaltlardan (kalk-alkalen) alınan, magma odasısüreçlerinin önemli bir kaydedicisi olan plajiyoklazların dokusal ve kimyasal zonlanması incelenmiştir ve dokusal mineral stratigrafilerimagma odası süreçlerini aydınlatmak için oluşturulmuştur. Anklav içeren andezitler ve anklavları içindeki plajiyoklazlar genellikleçekirdekten kenara farklı bir bileşim sergilemektedir. Anklavda bileşim oligoklaz-labradorit (çekirdek:An25-72) arasında değişirken, anakayaçta andezinden labradorite (çekirdek:An46-64) kadar değişmektedir. Ana kayadaki plajiyoklazların çoğunlukla yuvarlaklaşmış veAnortit, Fe, Mg, Sr ve Ba ile ters ve salınımlı zonlu olması dikkat çekicidir. Ancak anklavlarda yer alan plajiyoklazlar genellikle inceelek ve kirli yüzeyli elek dokusu sergilerler. Kalk-alkalen bazaltlardaki plajiyoklaz mikro-fenokristalleri, çekirdekten kenara bileşimdeandezin-labrador (An32-66) bileşimindedir. Dikkat çekici bir şekilde, bazaltlardaki plajiyoklazlar, An, Fe, Mg, Sr ve Ba ile ters vesalınımlı zonlanma gösterirler ve ayrıca cam ve mikrolitik kapanımlarla iri taneli elek dokusu ve süngerimsi hücresel dokular sergilerler.An, Fe, Mg içerikleri ile birlikte incelendiğinde bazaltlardaki bazı plajiyoklazların fenokristalden ziyade ksenokristal olabilecekleri ilerisürülmektedir. Plajiyoklazların dokusal ve kimyasal özellikleri göz önüne alındığında, bazaltik kayaçlarda ters ve salınımlı zonlanmaoluşumunda, magma karışımı işlemlerinin (magma karışımı/kendi kendine karışma) yanı sıra dekompresyon süreçleri de bazaltların oluşumunu etkilemektedir. Bununla birlikte, andezitik kayaçların oluşumunda, magmanın yeniden beslenmesi süreçleri, dekompresyonveya sıcaklık-basınç değişiminden daha ziyade anahtar bir role sahiptir.
