In a matrix of basaltic rock we can see white acicular crystals of ettringite with small crystallizations of calcite, found between the Ettringer Bellerberg and Büden mountains, specifically in Caspar quarry.

Methacrylate box included.

Would it be too much to ask for help on what a fusion of Sunstone and either a Yellow Pearl, Yellow Opal, or Bumblebee Jasper would look like?

So Sunstone + yellow Pearl = ?

Sunstone + yellow Opal = ?

And sunstone + bumblebee Jasper = ?

Thank you!

no not at all!, hopefully this fulfills your request!

Sunstone + Yellow Pearl - Corkite - Montebrasite - Ettringite

Sunstone + Yellow Opal - Alacranite - Childrenite -  Francevillite

Sunstone + Bumblebee Jasper - Rauvite - Septarian - Schalenblende

Manganite on Ettringite

Rare and fragile, these beautiful hexagonal crystals in the photo comes from the only source of this gemmy yellow sulphate mineral: The N'Chwaning Mines in South Africa's Kalahari manganese fields. Elsewhere it occurs as microcrystals, usually white to colourless. The mineral needs careful storage, since it is hydrated, and as water evaporates from the structure the colour turns white. It was first discovered in the Eifel Volcanic Field in Germany (see http://on.fb.me/1nJ2QtO), named in 1874 for the Ettringer volcano that spouted the lava flows which are its type locality. It forms when volcanic rocks intrude into limestones and freeze, baking the surrounding rock into a contact metamorphic aureole and spitting out element laced juices as they slowly freeze. This produces an exotic chemistry as the distillations of crust or mantle encounter limey rocks, forming a mineralogy known as skarns. Here the yellow Ettringite on matrix is accompanied by a lovely octahedron of Manganite, the most common oxide of this element.

Utilization of Nano-Grain Size Particles of Natural Perlite Rock in Blended Cement-Part II: Durability Against Sulfate Attack_Crimson Publishers

Utilization of Nano-Grain Size Particles of Natural Perlite Rock in Blended Cement-Part II: Durability Against Sulfate Attack by Darweesh HHM* in Crimson Publishers: Peer Reviewed Material Science Journals 

The chemical resistance or durability of Portland cement pastes (PS0) incorporating natural Perlite rock (PT) against the aggressive attack of 4% MgSO4 solution up to 12 months were investigated. Results showed that water of consistency and setting times (initial and final) are elongated. The compressive strength slightly improved during the early ages of immersion only up to three months with the blank cement batch (Pp0), but up to 4, 5, 6 and 7 months with cement batches (Pp1-Pp4) containing 5, 10, 15 and 20wt%PT, respectively and then decreased. Thereafter, certain deleterious or detrimental reactions started till forming high levels of ettringite and/or gypsum. These new phases are responsible for the decrease of compressive strength. Both combined water and total sulfate contents increased with time of immersion up to 12 months but decreased with PT content if compared with those of the blank (Pp0). The blank cement pastes (Pp0) recorded the highest values of total sulfate content, i.e. it is very sensitive to SO42- ions. At the end of the 12th month of immersion, the SO42- ions only precipitated on the external and lateral surfaces of the hardened cement pastes, and some horizontal minor cracks and little deformation could be seen on the edges of specimens with samples containing PT, whilst large swelling was noted with cement pastes of the blank (Pp0).

Hashemite: BaCr6+O4; Ettringite: Ca6Al2(SO4)3(OH)12·26H2O

Locality: Lisdan-Siwaga Fault, Hashem region, Amman, Jordan

“Group of brown, slightly greenish, sharp, transparent crystals of hashemite on matrix with lemon-yellow prisms of chromate-bearing ettringite. Also present, but not in the photographs are crystals of calcite. This is from the type locality for hashemite approx. 60 km southeast of Amman, Jordan. Specimen acquired from Jason B. Smith”. Andreas Schloth
