Granite is granite so there is no significant quality difference in the stone.
Our paper highlights the interpretative problems posed by difficult-to-analyse raw materials such as quartzite, and stresses subjectivity present in stone-tool technological studies, which may contribute to explain differences in the interpretation of Early Stone Age lithic assemblages.
Although the western part of the southern plains has a uniform volcanic origin, there are local differences in the colour, texture, and stone content of the region's soils.
This indicates differences in the control of peach stone formation and Arabidopsis dehiscence [ 17].
For some time, archaeologists have recognized that differences in the physical properties of different stone raw materials (e.g. hardness, brittleness, granularity) may have an influence on the final form of stone tools [88].
Differences in the physical composition of the stones are nearly undetectable.
The cellular and molecular factors contributing to these sex differences in kidney stone risk are incompletely understood.
Thus, EVs may mediate or reflect aspects of kidney stone pathogenesis and perhaps provide clues regarding sex differences in kidney stone incidence rates.
He aims to capture local flavor wherever he is, even if the differences among the stones in question wouldn't be appreciable to the untrained eye.
Differences in previous study results are likely attributable to the differences in the sizes and numbers of stones in the patients examined.
