Appinite describes intrusive igneous rocks that are rich in the hornblende series amphiboles and are thus mafic to ultramafic (rich in magnesium and iron). Appinites are ultrapotassic meaning that their feldspars are enriched with potassium relative to sodium, and they are uncommon, typically forming in plutons at considerable depth.
Appinite is a subset of lamprophyre, and as such it does not readily fit into established classification schemes. The unusual mineralogy and geochemistry of lamprophyres has led researchers to place them in a separate class. Historically, lamprophyre became a catchall category for rocks of various geneses that were difficult to categorize since they were defined neither by their quartz content nor their origin. The debate is ongoing.

How do particles in rocks fit together?
Particles in rocks fit together through a process called lithification, where sediments are compacted and cemented together. The size, shape, and arrangement of the particles determine the texture and structure of the rock. Different types of rocks, such as sedimentary, igneous, and metamorphic, have distinct characteristics based on how their particles are arranged.
How does leaching fit into the rock cycle?
Leaching is a process where water dissolves and carries away minerals from rocks, which can alter the rock's composition. This dissolved material may eventually be redeposited elsewhere in the environment through precipitation or be incorporated into new rocks, completing the cycle by contributing to the formation of new rocks.
The way the pieces of materials in the rock fit together define its?
texture. Texture describes the relative size, shape, and arrangement of mineral grains or crystals within a rock, which can range from fine and smooth to coarse and rough. This characteristic is helpful in identifying and classifying different types of rocks.
Are metamorphic rocks more dense than sedimentary or igneous rocks?
Igneous rocks are denser than sedimentary rocks because the particles and materials making up the igneous rock are more closely packed and compacted making more matter able to fit into a tiny area of its structures.
What rocks don't contain minerals?
most rocks from what i know contain minerals especially sedimentary rocks. and don't all rocks eventually become sedimentary rocks so really don't they all contain minerals to some extent :) hope it helped (by the way i am only a gcse student)

Is it difficult to fit real organisms into any classification scheme?
It is difficult to fit real organisms into any classification scheme because these classes are constructed just for convenience.

What kingdom was divided to create the six kingdom model classification?
The kingdom Protista was divided to create the six kingdom model classification. This division was made to provide a more organized and accurate classification system for organisms that did not fit well into the existing kingdoms of animals, plants, and fungi.
Does rock contain organic material?
If the reference is to a compound containing carbon, then many rocks would fit the definition and many would not. If the reference is to a rock that is partially derived from living things, then there are also rocks that would fit that definition, like coal or limestone for instance.
What is made of rocks?
Rocks are made of grains that fit together.
What is the classification of alge?
Algae is classified based on it's molecular composition. It is placed in the Kingdom eukaryotes with those who do not fit in the others kingdoms.
