- Nodular is used to describe a sediment or sedimentary rock composed of scattered to loosely packed nodules in matrix of like or unlike character. It is also used to describe mineral aggregates that occur in the form of nodules, e.g. colloform mineral aggregate with a bulbed surface.
en.wikipedia.org/wiki/Nodule_(geology)
In geology and particularly in sedimentology, a nodule is a small, irregularly rounded knot, mass, or lump of a mineral or mineral aggregate that typically has a contrasting composition from the enclosing sediment or sedimentary rock. Examples include pyrite nodules in coal, a chert nodule in limestone, or a phosphorite nodule in marine shale.

An unusual lump on your tree may be a gall. They appear on leaves, twigs, and branches, ranging in size from tiny bumps to massive growths that are hard to miss. Some are uniquely conical in shape. The way they look depends on what causes them, but they’re most commonly formed by insect feeding or egg laying and appear red, green, yellow, or black ...
Burls are identifiable by their appearance: a large, knobby growth on a tree trunk or branch, developed as a protective response to tree disease, and covered in bark. They’re not inherently harmful to the tree, but they are thought to reduce a tree’s vigor - although not as much as a rampant disease would. In the greater Kansas City area, we often ...
When fungal spores come in contact with a susceptible tree, they grow and feed on it. A certified arborist can identify the fungus type to determine how to best treat your tree, if it is necessary. It can be hard to determine whether your tree’s issue is fungal, especially because not every type of fungus is visible above ground, and not all fungi ...

Nov 8, 2022 · Septarian nodules are a type of concretion where mudstone of some kind is interspersed with calcite or another carbonate-rich mineral. The calcite portions follow the pattern of radiating cracks, which occur during the unique creation of these formations.
Concretions are compact, often rounded, accumulations of mineral matter that form inside sedimentary rocks such as shale and sandstone or in soil.
Nov 28, 2023 · Welcome to a comprehensive guide on galls—those enigmatic, often perplexing growths found on plants and trees. In pursuing a pristine garden, encountering peculiar lumps, bumps, or abnormal structures might leave you wondering about their origin and impact on plant health. Fear not!
Nodule, rounded mineral concretion that is distinct from, and may be separated from, the formation in which it occurs. Nodules commonly are elongate with a knobby irregular surface; they usually are oriented parallel to the bedding.

Oct 15, 2018 · Geodes and nodules are two similar but slightly different kinds of rocks. A geode is hollow inside, whereas a nodule rock is solid. Both may contain various substances inside their centers, including crystals, metals or even petroleum. Geodes and nodules can be cut open to reveal their nature.
