Most devitrification spherulites are less than a centimeter in size, so these large ones, some over four meters in diameter, are most unusual. The spherulites are composed of laths that radiate from the center of the sphere. These are devitrification textures that formed in the glass during cooling. Here occurring within a thick layer of rhyolitic vitrophyre is a groundmass of obsidian, with exceptionally large spherical phenocrysts (spherulites). So devitrified glass contains a lot of uranium atoms, just sitting around unattached-an easy pick-up for oxygenated groundwater trickling through the now-devitrified tuff.Ī volcanic rock with larger crystals (phenocrysts) embedded in a glassy groundmass is called a vitrophyre. ( Vitric is the root referring to “ glass,” so to “ devitrify” means essentially the process of “un-glassifying.”) In the process, large, unwieldy atoms that don’t fit readily into the structure of the forming minerals are expelled. The glass also may spontaneously crystallize at some point by the process of devitrification.

Uranium diffuses out of the glassy tuff particles, dissolves in its oxidized form, and heads off in the groundwater. Groundwater encountering a tuff deposit on the surface is oxygen-rich, having dissolved oxygen from the atmosphere. Because glass is not stable, it is susceptible to leaching by water-losing atoms from the glass into surrounding water. The high viscosity of granitic magmas results in tuffs that crystallize as glass-magma that froze before it had time to form into mineral crystals. Introduction of Uranium to the Earth’s Surface Explosive eruptions of granitic magma fall back to earth as ash-fall deposits or volcanic tuff. These magmas, when nearing the surface, are likely to erupt explosively because of their high viscosity and water content. Magmas of granitic composition-those low in magnesium, iron and calcium, high in silica, sodium, and potassium – contain more uranium than other types. So what does this mean for uranium deposits? In an oxygen-starved environment, uranium’s solubility is greatly reduced and it can’t remain dissolved, dropping out of solution to form solids-commonly the mineral uraninite (UO 2). In its oxidized form, uranium is very soluble, and hence highly mobile, and able to dissolve in water, often traveling coupled with carbonate ions (CO 3 ions).

Where oxygen is scarce- reducing conditions-uranium tends to transform to its reduced state. Redox refers to the abundance of oxygen present, controlling the “reducing-oxidizing” conditions, hence the term “redox.” In an oxidizing environment, where abundant oxygen is available, uranium assumes its oxidized state. The most important factor in uranium’s behavior in the crust is its sensitivity to redox conditions. Uranium Geochemistry and the Mechanics of Uranium Deposits The uneven distribution is a function of factors involving the nature of the uranium atom and the characteristics of different types of rocks. The element is not evenly distributed throughout the crust, however, being concentrated in some types of rocks and depleted in others. Drop them in The Pit below.Uranium is a scarce element in the earth’s crust, occurring at an abundance of about 2 to 4 parts per million (ppm). Head through the exit to return to the Frontier. Smash the wood blocking your path in the next room to reach the exit. To reach the level’s exit smash the wooden wall blocking the right path below. Head to the left of the ability container and interact with the final hive there to open the level’s exit. Shake the containment container and squeeze inside to get the Xiphorrhea ability which allows you to smash wooden walls and slash enemies. Head to the left of these enemies to encounter the next ability we need to get.

Grab them and pull them to you below to easily complete this section. Open the gate and wait in the corner underneath the switch for them to walk above you. To defeat these enemies you want to hit them from either the side or the top. These enemies cannot be eaten and have a shield that makes attacking them from the front difficult. In the area that is closed in by the gate there is a new enemy type. In this next room you will see a switch on the left side of the room next to a closed gate.

From the second hive head back to the into the previous room and go up through the entrance on the ceiling.
