Lava composition and volcanic rocks

Lava composition and Volcanic rocks. In the previous section we described the basic types of volcanoes. Volcanic types are intriely connected with the types of mamga, lava and vocanic rock (also known as igneous rocks) composition which shape the volcano and the surrounding form in igneous rocks when molten magma or lava solidifies.

Basalt Rock | Formation, Properties, Composition, Uses

Basalt has a strict chemical definition. It is defined in the TAS diagram shown above. Basalt is an igneous rock that contains more than 45 and less than 52% of SiO2 and less than five percent of total alkalies (K2O + Na2O)3. Types of Basalt Basalt types: tholeiites vs alkali basalts.

Andesite Rock | Properties, Composition, Formation, Uses

Andesite is an intermediate subalkalic rock with SiO2 contents ranging between 57 and 63 wt. %, and Na2O + K2O contents around 5 wt. %. Intermediate rocks are also characterized by an increased CaO content compared to that in acidic rocks. Similar CaO contents (6 – 7 wt. %) are also typical for diorite – the plutonic equivalent of andesite.

It has a very low silica content 4045%, and very high MgO content (~18%). Another way to classify volcanic rocks is by the proportion of light and dark minerals. Using this classifiion igneous rocks can be subdivided into four main types: felsic, intermediate, mafic and ultramafic. These types are defined in more detail in the table below.

6 Igneous Rocks and Silie Minerals – Mineralogy

All igneous rocks are made of the same major elements, but elemental ratios vary. The most significant variations are the amounts of silica (SiO 2) present (see table). Most igneous rocks contain between 45 and 65 wt% silica. They range from lowersilica basalt and gabbro to highersilica rhyolite and granite.

Stone Testing

Stone Testing

For most tests, the stone specimens are tested dry. However, since the strength may vary when the stone is wet, the strength tests ( compressive strength, flexural strength, modulus of rupture) are sometimes performed using wet stone specimens. For the dry condition, the stone specimens are dried in an oven at 60°C

Basalt. Basalt is a mafic extrusive rock, is the most widespread of all igneous rocks, and comprises more than 90% of all volcanic rocks. Because of its relatively low silica content, basalt lava has a comparatively low viscosity, and forms thin flows that can travel long distances. It is also found as intrusive dikes and sills.
