Strictly speaking, granite is an igneous rock with a volume of between 20% and 60% and at least 35% of the total feldspar consisting of alkali feldspar, although the term "granite" is commonly used to refer to a wider range of coarse-grained igneous rocks with quartz and feldspar. The term "granite" is used for granite and a group of ...
GRANITE is a hard rock of volcanic origin and belongs to the group of plutonic rocks, which originates from solidified magma deep in the Earth's crust. As opposed to this, basalt forms from the rapid cooling of lava exposed at or very near to the surface of the Earth. Thus it …
Definition of ACV: Aggregate Crushing Value (ACV) gives an relative measure how the aggregate act under an gradually acting compressive load. Sieve Size: ACV is applicable for aggregates passing 14.0 mm sieve and retained on 10.00 mm sieve.
The Arabian Shield forms a series of tectonostratigraphic terranes composed of geochemically diverse early Neoproterozoic to Cambrian (~ 850–525 Ma) granitoids intruding volcanosedimentary basin assemblages.With a general younging towards the east (Stoeser and Camp, 1985, Stoeser and Frost, 2006, Stern et al., 2010, Johnson et al., 2011), the Shield is composed of …
(2) Natural Granite. Granite is the typical type of plutonic rocks, it consists of feldspar, quartz, a few dark—colored mineral, sand, mica. The main chemical propositions of the granite are SiO2 (65% ~ 70%), a little of Al2O3,CaO,MgO and Fe2O3, thus the granite is acid rock.

Plagioclase is a series of tectosilicate (framework silicate) minerals within the feldspar group. Rather than referring to a particular mineral with a specific chemical composition, plagioclase is a continuous solid solution series, more properly known as the plagioclase feldspar series. This was first shown by the German mineralogist Johann Friedrich Christian Hessel (1796–1872) in 1826.
Basalt is calcium rich it has not Potassium feldspar. 19. To measure percentage, a line the ruler to the edges of the rock represented by the circle and determine the percentages ranging from one end of the circle to the other end.

Figure 1 shows the particle size distribution of basalt, from which a bimodal particle distribution could be observed; one fraction in the size range of 0.2–5 μm with a maximum of 3 μm and another in the size range of 5–100 μm with a maximum of 40 μm were observed. It was also observed that 97% of basalt powder passed through the 200 ...
A detailed characterization of the pore space is crucial for understanding of transport and element transfer in rocks. Here, the effect of differences in texture and content of secondary minerals on transport in pore systems was determined for two rocks of widespread occurrence, mid-ocean ridge basalts (MORB) and granites. Pore space characteristics were analyzed by Hg-porosimetry, intrusion ...

Basalt and gabbro have a similar composition, just the crystal size differs from different cooling rates (same for rhyolite and granite). Diorite and Andesite Diorite is a plutonic igneous rock composed of coarse grains of plagioclase feldspar and less than 40 percent hornblende and biotite, or, more rarely, pyroxene or olivine.

The low range of hills west of Blessington, and the rest of the northwestern border of the county, are based on clay-slate. On the eastern side of the county, between the mica slate range and the sea, the prevailing rock is clay-slate, but in detached situations are found granite rising from beneath it, and quartz and trap rocks associated with it.
No mineral admixtures were added. In the mixtures with w/c = 0.45 and w/c = 0.28, superplasticizers (a mixture of polycarboxylic ether and calcium lignosulphonate) were used for similar mix consistency.To compare the mixtures with the same w/c ratios, the cement paste volume in 1 m 3 of the mixture was the same in all the mixtures. In this way, the amount of cement, water and sand in the ...

GRANITE. Granite is a volcanic stone composed of quartz and feldspar, mica, amphiboles and various minerals. It is called a volcanic stone as it results from the cooling of molten magma underground. During the heating and subsequent slow cooling process, granite is formed as an extremely hard material. The abundance and different variations of additional minerals allow the many different ...
The Railtrack line specification (Railtrack, 1998) specifies that the ACV should not exceed 22%. However, the ACV test is flawed because the tensile strength of ballast particles is a function of ...
K-feldspar crystals >5 cm in greatest dimension are common in calc-alkaline granites and granodiorites worldwide. Such megacrysts are generally interpreted as having grown to large sizes early in a magma's crystallization history while they were largely molten, owing to field relations such as megacryst alignment and megacryst-rich clusters and to crystallographic features such as zonally ...

Answer (1 of 2): Sure, why not? The earth is 4 billion years old, and any kind of rock can form just about anywhere. There is no reason for some existing rock to preclude the later existence of a different sort of rock. Also, since both those lithologies are igneous rocks, they may certainly for...
