Galena streak color.

Galena, Acanthite, and Skutterudite - Darker color, darker colored streak, usually in different form. Molybdenite and Stibnite - Softer (2), different crystal form. Lead - softer (1.5), oxidize s to a slight bluish-gray color.Minerals that are the same color may have a different colored streak. Many minerals, such as the quartz, do not have a streak. To check streak, scrape the mineral across an unglazed porcelain plate. Yellow-gold pyrite has a blackish streak, another indicator that pyrite is not gold, which always has a golden-yellow streak.

According to Bayo-ang (2016) streak is obtained by scratching the mineral on an unpolished piece of white porcelain called a streak plate. When the excess powder is blown away, what remains is the color of the streak. Streak is a more reliable property than color as streak shows the true color of minerals. It does not vary even if color does.

Answer to Solved Hardness = 5-6 Streak = Pale green to gray ifGalena is a lead sulfide mineral which can be silver in color with a metallic luster to a dull grey, with a streak of grey to black. Galena is part of the sulfide group of minerals because it contains sulfur and another element (lead) (King, 2022b).Easily recognized by it good cleavage, high specific gravity, softness, and lead-gray streak, this mineral is the primary ore mineral of lead. It is a very common sulfide that has been worked for its lead content as early as 3000 BC.

Study with Quizlet and memorize flashcards containing terms like Graphite, Galena, Pyrite and more.The streak of a mineral is its color in its powdered form, which more reliably identifies a mineral than its color in its solid form. The luster of a mineral is how the mineral reflects …However, hematite's streak is blood-red, while galena's streak is lead gray. Hematite (pictured above) is probably the most well known example of streak with its completely surprising streak color. Unfortunately for collectors, translucent minerals have, usually, a rather undiagnostic white streak.The luster of a specimen is usually communicated in a single word. This word describes the general appearance of the specimen's surface in reflected light. Eleven adjectives are commonly used to describe mineral luster. They are: metallic, submetallic, nonmetallic, vitreous, dull, greasy, pearly, resinous, silky, waxy, and adamantine. The color of the streak left behind can be very informative, and sometimes surprising. For example, the common mineral hematite, which is usually some shade of grey, leaves a red to reddish brown streak. However, the streak of most minerals is similar in color to that of the mineral in hand-sample (see the example of galena pictured below).Galena (PbS) Luster bright metallic. Color lead-gray. Hardness 2.5. Cubic cleavage. Streak lead-gray. High specific gravity. Veins and other ore deposits. Lead ore. Garnet (Fe, Mg, Ca, Al Silicate) Luster nonmetallic.
