- [REQUIRED] Please post a photo in your log of yourself or a personal item at the outcrop to prove you visited the site.
- Look at the marble outcrop. Do you see any evidence of metamorphosing and folding?
- What has the weathering done to the details of the outcrop? Do you see distinct patterns or is it rounded and smooth?
The sedimentary rocks here were deformed and metamorphosed, as huge volumes of molten rock flooded upward, intruding them. Rocks become deformed when the Earth's crust is compressed or stretched. In this case, molten describes the rocks that were reduced to liquid form by volcanic activity. It takes incredibly high temperatures to get an object that was once rock solid to be transformed into a liquid state.The forces needed to do this act over millions of years.This area's outcrops preserve some of New Brunswick's oldest rocks and also a terrane boundary separating parts of Ganderia and Avalonia. This chapter in Ganderia's story is preserved here as part of the Brookville terrane.
A terrane in geology, is a piece of crust which has been transported laterally, usually as part of a larger plate, and is relatively buoyant due to thickness or low density. It is a fragment of crustal material formed on, or broken off from, one tectonic plate and accreted or "sutured" to crust lying on another plate.
During this process, some of the rocks metamorphosed. Metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). ... Metamorphism produced with increasing pressure and temperature conditions is known as prograde metamorphism.
For this earthcache, we will be looking at a marble outcrop along Cedar Trail. The marble outcrops have carbonate minerals that are slightly soluble in water, and so are subject to chemical weathering in the maritime climate. Carbonate rocks form mineral coatings that cement the existing rock grains together or it can fill fractures when conditions are right for precipitation.Look for intricately folded traces of contrasting light and dark grey on the outcrop surface. When carbonate rocks are subjected to stress, they become hightly plastic and are easily distorted. The complex shapes are the remains of limestone bedding deposited about 600 million years ago, contorted by deformation and how-grade metamorphism in the subduction zone (550 to 525 million years ago).
Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite. In geology, the term marble refers to metamorphosed limestone.
