Structural Geology Course: Lecture 7 (Interpreting geological maps/Introduction to outcrop patterns)
Переглядів 121Місяць тому
Outcrop patterns are the visible exposures of rock formations on the Earth's surface. They represent areas where the underlying geology is exposed due to erosion, weathering, or tectonic activity. These patterns are crucial for interpreting geological maps because they provide direct evidence of the rock types, structures, and stratigraphic sequences present in a particular area. By analyzing o...
Structural Geology Course: Lecture 6 (River Valley Formation & Contours)
Переглядів 57Місяць тому
In structural geology, understanding river valleys and their contours is crucial for deciphering outcrop patterns and geological structures. River valleys are low-lying areas carved out by rivers over geological time periods, typically exhibiting a V-shaped profile in cross-section. These valleys are significant because they often expose underlying rock formations and geological structures thro...
Structural Geology Course: Lecture 5 (Continuity & Discontinuity in Structural Geology)
Переглядів 100Місяць тому
In structural geology, continuity and discontinuity are fundamental concepts that describe the spatial relationships between geological features and structures at different scales. Continuity refers to the uninterrupted extension of geological features across space, whereas discontinuity describes breaks or interruptions in the continuity of geological structures. Understanding these concepts i...

In structural geology, the concepts of homogeneity and heterogeneity refer to the uniformity or variability of rock properties at different scales, from the microscale to the macroscale. Homogeneous rocks have consistent properties throughout, such as uniform mineral composition, grain size, and texture. In contrast, heterogeneous rocks exhibit variability in their properties, often due to diff...
Structural Geology Course: Lecture 3 (Isotropic & Anisotropic Rocks)
Переглядів 71Місяць тому
In structural geology, rocks can be broadly categorized as either isotropic or anisotropic based on their mechanical and physical properties. Isotropic rocks exhibit uniform properties in all directions, meaning their properties, such as density, elasticity, and strength, are the same regardless of the direction in which they are measured. Anisotropic rocks, on the other hand, have properties t...

Scale in structural geology refers to the size at which geological structures are observed and studied. It encompasses a range of scales, from microscopic features such as mineral grains and fractures to regional-scale structures like mountain ranges and tectonic plate boundaries.

Types of Stable Isotope Fractionation: Kinetic vs. Equilibrium Fractionation
Переглядів 752 місяці тому
Equilibrium fractionation occurs when isotopes of an element are distributed between two or more substances in a reversible reaction, reaching a state of dynamic balance. At equilibrium, the isotopes are partitioned based on differences in their chemical bond strengths, often resulting in the heavier isotope being preferentially concentrated in the substance with the stronger bonds. This type o...
Stable Isotope Fractionation

Isotope fractionation refers to the process by which different isotopes of an element are separated or preferentially concentrated in different chemical or physical processes. This occurs because isotopes of an element have slightly different masses, leading to variations in their chemical behavior and physical properties. For example, lighter isotopes tend to react faster than heavier ones, wh...
Isochron Dating Technique: Radioactive & Radiogenic Isotopes

Isochron dating is a sophisticated radiometric dating method used to determine the age of rocks, minerals, and meteorites. Unlike traditional radiometric dating, which relies on the assumption that no daughter isotopes were present at the formation of the sample, isochron dating eliminates this assumption by using a graphical method to determine both the age and the original composition of the ...

      This is for demonstration purposes. But more or less the same. Wherein colors plays an important role during interpretation (e.g., red colors in magnetic methods may show the rock below the surface which are associated with high magnetic values, however, the opposite is true for blue colors).

      The red line represent the standard composition which serves as a frame of reference. This is either Mid-Oceanic Ridge Basalt or Chondrite which have known composition.Then any shift in composition from this line is an anomalous change (enrichment or depletion).

      That is true. Also, we know that quartz (crystalline silica) is a mineral containing silica (SiO2). Therefore, we can conclude that all quartz is silica but not all silica is quartz. This is because we also having a high temperature form of quartz called tridymite with the same composition.

    Why does some Labrorite form clear crystals?

    • @morakamalebati7698
      @morakamalebati7698 10 місяців тому

      The main reason why not all labradorites exhibit labradorescence (i.e., some are clear) is because of lamellar separation and composition. The requirement for lamellar separation is a very slow cooling of the rock containing the plagioclase. This slow cooling will enable Ca, Na, Si, and Al ions to diffuse through the plagioclase and produce the lamellar separation. The lamellar separation only occurs in plagioclases of a certain composition; those of calcic labradorite (50-70% anorthite and bytownite with an anorthite content of approximately 70-90%. Therefore, not all labradorites exhibit labradorescence (they might not have the correct composition and or/ they cooled too quickly), and not all plagioclases that exhibit labradorescence are labradorites (they may be bytownite).
