This document summarizes how rocks are classified based on their formation. There are three main classes of rocks: igneous, sedimentary, and metamorphic. Within each class, rocks can be further classified based on their composition, texture, and grain size. Igneous rocks form from cooled lava or magma, and can be intrusive or extrusive based on where they solidify underground or above ground, affecting their grain size. Sedimentary rocks form from cemented sediments like grains, shells, and fossils. Metamorphic rocks have foliated or non-foliated textures indicating the process that altered the original rock.

Igneous rocks are formed by the cooling or solidification of magma or lava.
Sedimentary rocks are formed by the compaction and cementation of sediments, a process called lithification.
Metamorphic rocks are formed by preexisting rocks that are exposed to extreme heat and pressure in the
Earth’s interior, a process called metamorphism.

The main difference between Igneous, Sedimentary and Metamorphic rocks, is the way that they
are formed, and their various textures.
Igneous Rocks
Igneous rocks are formed when magma (or molten rocks) cool down, and become solid. High
temperatures inside the crust of the Earth cause rocks to melt, and this substance is known as
magma. Magma is the molten material that erupts during a volcano. This substance cools down
slowly, and causes mineralization to take place. Gradually, the size of the minerals increase until
they are large enough to be visible to the naked eye. Igneous rocks are mostly formed beneath
the Earth’s surface.
The texture of Igneous rocks can be referred to as Phaneritic, Aphaneritic, Glassy (or vitreous),
Pyroclastic or Pegmatitic. Examples of Igneous Rocks include granite, basalt and diorite.
Sedimentary Rocks
Sedimentary rocks are usually formed by sedimentation of the Earth’s material, and this
normally occurs inside water bodies. The Earth’s material is constantly exposed to erosion and
weathering, and the resulting accumulated loose particles eventually settle, and form
Sedimentary rocks. Therefore, one can say, that these types of rocks are formed slowly from the
sediments, dust and dirt of other rocks. Erosion takes place due to wind and water. After
thousands of years, the eroded pieces of sand and rock settle, and become compacted to form a
rock of their own.
Sedimentary rocks range from small clay-size rocks to huge boulder-size rocks. The textures of
Sedimentary rocks are mainly dependent on the parameters of the clast, or the fragments of the
original rock. These parameters can be of various types, such as surface texture, round, spherical
or in the form of grain. The most common type of Sedimentary rock is the Conglomerate, which
is caused by the accumulation of small pebbles and cobbles. Other types include shale, sandstone
and limestone, which is formed from clastic rocks and the deposition of fossils and minerals.
Metamorphic Rocks
Metamorphic rocks are the result of the transformation of other rocks. Rocks that are subjected to
intense heat and pressure change their original shape and form, and become Metamorphic rocks.
This change in shape is referred to as metamorphism. These rocks are commonly formed by the
partial melting of minerals, and re-crystallization. Gneiss is a commonly found Metamorphic
rock, and it is formed by high pressure, and the partial melting of the minerals contained in the
original rock.
Metamorphic rocks have textures like slaty, schistose, gneissose, granoblastic or hornfelsic.

(May 29th, 2024) Advancements in Intravital Microscopy- Insights for Preclini...Scintica Instrumentation
Intravital microscopy (IVM) is a powerful tool utilized to study cellular behavior over time and space in vivo. Much of our understanding of cell biology has been accomplished using various in vitro and ex vivo methods; however, these studies do not necessarily reflect the natural dynamics of biological processes. Unlike traditional cell culture or fixed tissue imaging, IVM allows for the ultra-fast high-resolution imaging of cellular processes over time and space and were studied in its natural environment. Real-time visualization of biological processes in the context of an intact organism helps maintain physiological relevance and provide insights into the progression of disease, response to treatments or developmental processes.
In this webinar we give an overview of advanced applications of the IVM system in preclinical research. IVIM technology is a provider of all-in-one intravital microscopy systems and solutions optimized for in vivo imaging of live animal models at sub-micron resolution. The system’s unique features and user-friendly software enables researchers to probe fast dynamic biological processes such as immune cell tracking, cell-cell interaction as well as vascularization and tumor metastasis with exceptional detail. This webinar will also give an overview of IVM being utilized in drug development, offering a view into the intricate interaction between drugs/nanoparticles and tissues in vivo and allows for the evaluation of therapeutic intervention in a variety of tissues and organs. This interdisciplinary collaboration continues to drive the advancements of novel therapeutic strategies.
Richard's entangled aventures in wonderlandRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.
The increased availability of biomedical data, particularly in the public domain, offers the opportunity to better understand human health and to develop effective therapeutics for a wide range of unmet medical needs. However, data scientists remain stymied by the fact that data remain hard to find and to productively reuse because data and their metadata i) are wholly inaccessible, ii) are in non-standard or incompatible representations, iii) do not conform to community standards, and iv) have unclear or highly restricted terms and conditions that preclude legitimate reuse. These limitations require a rethink on data can be made machine and AI-ready - the key motivation behind the FAIR Guiding Principles. Concurrently, while recent efforts have explored the use of deep learning to fuse disparate data into predictive models for a wide range of biomedical applications, these models often fail even when the correct answer is already known, and fail to explain individual predictions in terms that data scientists can appreciate. These limitations suggest that new methods to produce practical artificial intelligence are still needed.
In this talk, I will discuss our work in (1) building an integrative knowledge infrastructure to prepare FAIR and "AI-ready" data and services along with (2) neurosymbolic AI methods to improve the quality of predictions and to generate plausible explanations. Attention is given to standards, platforms, and methods to wrangle knowledge into simple, but effective semantic and latent representations, and to make these available into standards-compliant and discoverable interfaces that can be used in model building, validation, and explanation. Our work, and those of others in the field, creates a baseline for building trustworthy and easy to deploy AI models in biomedicine.

Classification of Igneous rocks
1. Rock Classification
Rocks are divided into three main
classes based on how they form:
1. Igneous
2. Sedimentary
3. Metamorphic
Each type of rock can be further
classified based on:
Composition and texture
2. Composition
The chemical make up of the rock or
what it is made of.
This can be minerals or other
materials: shells, clay, plants,
sand, pebbles
3. Texture/Grains
Determined by the grains size, shape
and position.
Igneous can be fine or coarse grain
Sedimentary can be characterized by
observing lithified (cemented) inorganic
grains, minerals, organic material, or
fossil fragments. The wide range of
textures common in sedimentary rocks is
separated into clastic, chemical, and
bioclastic (biochemical) groups.
