The aim of this study
is to conduct a detailed geological, petrographic, and mineralogical analysis
of the basaltic pumice and lava outcrops located in Türkmen town, Toprakkale district,
Osmaniye Province. The conducted analyses reveal the mineralogical and
petrographic composition and textural characteristics of these rocks, with the
existing mineral structures being identified in detail. The basalts in the
study area are generally classified into three types: pyroclastic, vesicular
basalts (pumice), and columnar (massive) basalts. The first type, described as
pyroclastic rocks, consists of volcanic pumice, tuff, and volcanic bombs, with
diameters reaching up to approximately 1 meter. The second type of volcanic
product is represented by vesicular pumice layers. In the lower levels of pumice-rich
rocks, massive structures have been observed. These basalts generally exhibit
intergranular porphyritic and ophitic textures, with pumice-type rocks
containing abundant cooling vesicles. The massive basaltic rocks, which lack
vesicles, are composed of olivine, pyroxene, and plagioclase microlites, and
are found as a layer of 1.5 to 2.2 meters in thickness, overlying the pumice-type
volcanic rocks.
