Well, apparently it is, when our granite is not natural. Now, with "desquamation" we have some sort of a proof that these columns were indeed made using artificial granite. Really, why would you spend time to quarry some 800 ton slab of granite, transport it to a city, and then spend time shaping, and lifting it.

Granite is a rock and is therefore composed of several types of minerals. Granite is mostly alkali feldspar and quartz, with other minerals being accessories or accidentals. The chemical formulas for alkali feldspars include KAlSi3O8, which is orthoclase; (K,Na)AlSi3O8, which is sanidine; and KAlSi3O8, which is microline.

Granite: Granite is the most widely distributed rock in igneous rock, which belongs to hard stone.It is composed of feldspar, quartz and mica. Its composition is mainly silica, accounting for 65% – 75%.The rock is hard and dense, and can be divided into three kinds of "pegmatite", "coarse crystal" and "fine crystal" according to the size of its crystal particles.
