 | Geological Research with Dr. Leon Long Dr. Leon Long is a professor in the Department of Geological Sciences at the University of Texas. Dr. Long's research is in isotope geology, especially to use naturally occurring radioactivity and its daughter products as a geologic clock (e.g., to date the crystallization of a magma), and as a geochemical tracer (e.g., to characterize the source rock whose melting produced the magma). Dr. Long is interested in applying the Rb-Sr isotopic age method to clay minerals, one possibility being to date when weathering had produced an ancient soil zone. |

The series host was Dr. David Pearson English trained, Canadian geologist residing in Sudbury, Ontario. Dr. David Pearson lectured at Laurentian University in Sudbury, Ontario. This Canadian Series was made in 1976 - Understanding the Earth by TV Ontario. This series was part of a extension course at Laurentian, i believe from 1976 to 1986. The entire series was 22 episodes. This series illustrated manual demonstrations in geological process.

 | Fountain Paint Pot Fountain Paint Pot is one of many mudpots found in the park. In early summer the mudpots are thin and watery from abundant rain and snow. By late summer they are quite thick. The mud is composed of clay minerals and fine particles of silica. In this area the rock is rhyolite, which is composed primarily of quartz and feldspar. Acids in the steam and water break down the feldspar into a clay mineral called kaolinite. |

 | Mineral Makeup Ingredients: Fillers Part 2 Follow on to Fillers Part 1. Some secondary ingredients: Mica and Methicon - slip, adhesion, translucent. NOT SCARY. :) Coated Mica with Methicon which is a type of Silicone. Reduces the appearance of pores and fine lines. Rice Powder: Alternative to Talc or Cornstarch. Does expire, most likely good up to a few years. lightweight, translucent, absorbent. Good for making Minerals Veils. Kaolin Clay: medium coverage -- "sorry I said it was translucent." :( Highly absorbent, and adhesive. Silica Powder: silky smooth, translucent, highly absorbent. Magnesium Stearate: Very high adhesion, average coverage, and slip. Vegetable derived, not a mineral. Authentic Silk Powder: Absorbent, Moisture-adjusting, reflects UV rays, add sheen, and contains 18 amino acids. My Favorite! Great for Veils and Foundations. |
 | Digging holes...Caliche Rocks!!! ...Making dirt This is a documentation of Spirit Mountain Herbal Gardens in Arizona 3/21/2008 Caliche (mineral) Caliche is a hardened deposit of calcium carbonate. This calcium carbonate cements together other materials, including gravel, sand, clay, and silt. It is found in aridisol and mollisol soil orders. Caliche occurs worldwide, generally in arid or semi-arid regions, including in central and western Australia, in the Kalahari Desert, in the High Plains of the western USA, and in the Sonoran Desert. Caliche is also known as hardpan, calcrete, kankar (in India), or duricrust. The term caliche is Spanish and is originally from the Latin calx, meaning lime. Caliche is generally light colored but can range from white to light pink to reddish-brown, depending on the impurities present. It is generally found on or near the surface, but it can be found in deeper subsoil deposits as well. The layers can vary from a few inches to feet thick, and multiple layers can exist in a single location. In northern Chile and Peru, caliche refers to the nitrate salt deposits of the Atacama Desert. Caliche can also refer to various clayey deposits in Chile, Peru, Mexico, and Colombia. In addition, it has been used to describe some forms of quartzite, bauxite, kaolinite, laterite, chalcedony, opal, and soda niter. Similar material, but composed of calcium sulfate rather than calcium carbonate, is called gypcrust or gypcrete ("Gyp-Crete" is also a trademarked brand name). How it forms Caliche generally forms when minerals are leached from the upper layer of the soil (the A horizon) and accumulate in the next layer (the B horizon), at depths of approximately 3 to 10 feet under the surface. Caliche generally consists of carbonates in semiarid regions, while in arid regions, less soluble minerals will form caliche layers after all the carbonates have been leached from the soil. The calcium carbonate that is deposited accumulates, first forming grains, then small clumps, then a discernible layer, and finally a thicker, solid bed. As the caliche layer forms, the layer gradually becomes deeper, eventually moving into the parent material, which lies under the upper soil horizons. However, caliche can also form in other ways. It can form when water rises through capillary action. In an arid region, rainwater will sink into the ground very quickly. Later, as the surface dries out, the water below the surface will rise, carrying dissolved minerals from lower layers upward with it. This water movement forms a caliche that tends to grow thinner and branch out as it nears the surface. Plants can contribute to the formation of caliche as well. The plant roots take up water through transpiration, leaving behind the dissolved calcium carbonate, which precipitates to form caliche. Caliche can also form on outcrops of porous rocks or in rock fissures where water is trapped and evaporates. In general, caliche deposition is a slow process, but if enough moisture is present in an otherwise arid site, it can accumulate fast enough to block a drain pipe. While the formation of other caliches is relatively well understood, the origin of Chilean caliche is not known definitively. One possibility is that the deposits were formed when a prehistoric inland sea evaporated. Another theory is that it was deposited due to weathering of the Andes Caliche and Gardening Problems caliche cause Caliche beds can cause many problems when trying to grow plants. First, an impermeable caliche layer prevents water from draining properly, which can keep the roots from getting enough oxygen. Salts can also build up in the soil due to the lack of drainage. Both of these situations are detrimental to plant growth. Second, the impermeable nature of caliche beds also prevents plant roots from going through the bed, which means the roots have a limited supply of nutrients, water, and space, so they cannot develop normally. Third, caliche beds can also cause the surrounding soil to be basic (have a high pH). The basic soil, along with calcium carbonate from the caliche, can prevent plants from getting enough nutrients, especially iron. An iron deficiency will cause the plant's youngest leaves to become yellow. Soil saturation above the caliche bed can make the condition worse. Fixing these problems The best solution to these problems is to remove the layer of caliche and replace it with a mixture of organic material and soil. The hole should be large enough to contain the plant's mature root system and should go entirely through the caliche layer. However, when the caliche layer is thick, dig a hole large enough for the mature root system. Then, a smaller hole or holes can be dug through the remaining caliche to provide drainage. To test drainage, the hole should be filled with water. If the level drops by 1 inch per hour, the drainage is sufficient. |
