πŸ‡¬πŸ‡§ Usually, the term enclave is associated with a territory with political and cultural distinctions whose geographic borders are completely within the limits of another territory. In Europe and in terms of entire nations included in the territory of another country, two enclaves are known: the Republic of San Marino and the Vatican City. Both enclaved within Italy.

The word enclave is French and first appeared in the mid-15th century as a derivative of the verb enclaver (1283), from the colloquial Latin inclavare (to close with a key). Originally, it was a term of property law that denoted the situation of a land or parcel of land surrounded by land owned by a different owner, and that could not be reached for its exploitation in a practical and sufficient manner without crossing the surrounding land.

In geology, an enclave is an aggregate of minerals or rock observed inside a larger rock body. Usually, it refers to such situations in plutonic rocks. Micro-granular enclaves in felsic plutons result from the introduction of mafic magma into the magma chamber and its subsequent cooling following incomplete mixing. Roughly it can be divided in four types of enclaves: xenoliths, microgranular enclaves, magma mixture and micaceous enclaves (restites).

πŸ‡¬πŸ‡§ These enclaves are characterized by having normally rounded or ellipsoidal shapes, having a texture between porphyritic and equigranular with a tendency to fine grain and a high content of mafic minerals. They are typical of granites, and their origin is also igneous (basic magma), which is why they can be considered proof of magma mixing (without reaching intermediate terms).

They usually correspond to rocks of the dioritic, tonalitic or granodioritic type. The fact that the contacts are rounded or sinuous implies that they were totally or partially molten when they were included in the granitic magma. Two examples of microgranular enclaves included in monzogranites can be seen in the upper images. The porphyritic texture can be appreciated in both cases, with feldspar phenocrysts. The contacts are quite clear, although in the left image a felsic, feldspathic halo can be sensed, perhaps of reactional origin.

The microgranular enclaves can be mixed to a lesser or greater degree with the granitic melt. When they do, their contacts are transitional and their form more irregular. The left image shows a more "digested" enclave with irregular contact, larger grain size and less mafic. The right image shows a rounded shape, net contact and a greater abundance of biotite on the edges, developing a quartz-feldspathic halo. This shape can be caused by the viscous flow of the two melts, or also by deformation of the intrusion.

πŸ‡¬πŸ‡§ Igneous minerals are minerals that form through the crystallization of molten rock material, either magma beneath the Earth's surface or lava erupted at the surface. As the molten rock cools, minerals begin to crystallize in a specific order depending on their chemical composition and melting points. This process leads to the formation of igneous rocks such as granite, basalt, and gabbro.

Common igneous minerals include quartz, feldspars (orthoclase and plagioclase), amphibole, pyroxene, olivine, and biotite. These minerals can help geologists determine the conditions under which a rock was formed, such as depth, pressure, and temperature. The color, hardness, crystal shape, and other physical properties of these minerals also influence the appearance and classification of the rock.

Igneous minerals are generally divided into two main groups based on their chemical composition: felsic and mafic. Felsic minerals, like quartz and orthoclase, are rich in silica and aluminum and are typically found in lighter-colored rocks like granite. Mafic minerals, such as pyroxene and olivine, contain higher amounts of iron and magnesium and are common in darker rocks like basalt.

1) Describe in your own words what is an enclave.

2) Based on your observation in the terrain, is the contact between the enclaves and the parent rock regular or irregular? Why do you think that?

3) In relation to the parent rock, is the color of the enclaves darker or lighter?

4) Take a photo of you or your GPS device with the enclaves on the initial coordinates and attach it to your log.
