14045 (8) Regolith breccia

Samples 14041–14046 are fragments from a fractured clod that broke apart when it was collected. 14045 is a blocky, subangular rock with a rough, hackly surface. Glass-lined zap pits occur on all but one surface. The sample is a friable, fine-grained clastic rock with very sparse sub-angular light-colored clasts in a medium-grey matrix.

The sample weighed 65.2 grams before analysis. It has not been dated.

Our thin section contains many fragments of irregularly-shaped glass of variable colour and composition. A large (0.3 mm) spherical glass globule can be seen in rotation 1. Throughout the section small fragments of anorthositic material are commonly found (see rotation 2 for one of them.

About this collection

The Apollo 14 landing site was in a region formed by impact-basin debris.

Most of the 42 kilograms of rocks and soil collected on Apollo 14 are breccias (rocks that are composed of fragments of other, older rocks). In some cases, the rock fragments that form a breccia are themselves breccias. Such rocks obviously have experienced complex histories with multiple generations of impact events. Some breccias were heated enough that some of the material in the rock was melted. 

Apollo 14 was launched on 31 January 1971.

Title
Refers to any word or phrase that appears in the individual rock names. Names are generally descriptive; they allow users to search for broad terms like ‘granite’ as well as more specific names such as ‘breccia’. However, the adjacent descriptions of the specimens captures a wider range of general words and phrases and is a more powerful search tool.
Description
Refers to any word or phrase that appears anywhere in the descriptions of the specimens
Accessory minerals
Minerals that occur in very low abundance in a rock. They are usually not visible with the naked eye and contribute perhapssver, they often dominate the rare elements such as platinum group metals.
Rock-forming minerals
Minerals that make up the bulk of all rock samples and are also the ones used in rock classi?cation.
Timescale
Selecting one or more period, for example 'Jurassic'.
Theme
A term used to group together related samples that are not already gathered into a single Collection. For instance, there is a ‘SW England granites’ theme that includes such rock types as granite, hydrothermal breccia, skarn and vein samples.
Category
A general term used to label a rock sample. It is a useful way of grouping similar samples throughout a collection. Category names are often, but not exclusively, common rock names (e.g. granite, basalt, dolerite, gabbro, greisen, skarn, gneiss, amphibolite, limestone, sandstone).
Owner
The owner of the sample that appears in the collection. For example, NASA owns all the samples that appear in the Moon Rocks collection
