Since the early 18th century these fascinating rock formations have been considered one of the world’s geological curiosities and wonders. I’m a rock hound and I collect rocks ...

In sedimentary rocks, Geodes form when organic matter decays and leaves behind a void in the host rock. Over time, mineral-rich water from the surrounding host rock begins to seep into the cavity. As carbonate minerals precipitate out of solution, crystals begin to form inside the hollow creating a sedimentary Geode. Celestite Geode.The forces of wind, water, and time constantly work to shape rocks into a range of shapes, sizes and colours — including ones that look like past life. Scientists call these features pseudofossils. Pseudofossils are formed by inorganic (non-living) processes but look like fossils or other signs of life.On the rocks cocktails have been a popular drink choice for many years, but their origins can be traced back to the early 1800s.

From geologists to casual observers, many have wondered why ...

When concretions form in clay they are usually due to carbonates, or less commonly silica, sulphates or pyrite, growing in the matrix, sometimes cementing grains and sometimes pushing them away. So they may contain a lot of clay, silt or sand inclusions, often dominating over the matrix, but are usually named for the cementing material.Rhyolite (Early Proterozoic) at surface, covers 0.4 % of this area. Ash-flow tuffs and interbedded volcaniclastic sedimentary rocks and cogenetic granite (unit Xga) exposed as inliers in southern Wisconsin. In central Wisconsin pink, flow-banded rhyolite and chert-cemented breccia inferred to be 1760 Ma. Image by: Andy Fyon, Aug 12, 2019. The rocks that contain the concretions are about 80 million years old. The rocks consist of shale, sandstone, iron-rich rock, and clay-rich deposits. These rocks were deposited, as sediments, on the bottom and edges of an ancient north-south ocean that divided western Canada from central Canada about 80 ...

Slow chemical changes, perhaps related to microbial activity, cause minerals to come out of the groundwater and seal the sediment together. Most often the cementing mineral is calcite, but the brown, iron-bearing carbonate mineral siderite is also common.A concretion is a hard, compact mass formed by the precipitation of mineral cement within the spaces between particles, and is found in sedimentary rock or soil.
