摘要
本研究的目的是分析位于Piraí do Sul, paran市岩石艺术遗址附近的岩石支架中沉淀的矿物,以便通过鉴定次生矿物来检测可能的矿物学变化。结果表明,这些矿物来自与降雨有关的重要风化活动,以及通过热液作用改变矿床的矿物的作用。这些结论指出,这些矿物的广泛存在,部分原因是由于雨水与有机物(地衣、微生物)相互作用的化学风化过程造成的岩石支撑的改变。
The materiality of things: First results of diffractometry and spectrometry analyzes on secondary mineral precipitations associated with rock art in Piraí do Sul, Paraná, Brazil
This study aimed to analyze the minerals precipitated in rocky supports located close to sites with rock art in the municipality of Piraí do Sul, Paraná, in order to detect possible mineralogical variations from the identification of secondary minerals. The results point to the existence of minerals from important weathering activities related to rainfall and the action of minerals that alter deposits with hydrothermal action. The conclusions point to the widespread existence of these minerals that result, in part, from the alteration of the rocky support caused by chemical weathering processes by the action of rain in interaction with organic matter (lichen, microorganisms).
