  quartz-tourmaline
     Quartz-tourmaline veins and associated greisen selvedges (quartz-muscovite-rutile in granite, quartzmuscovite-tourmaline in metasediments) are restricted to, and apparently pcstdate, the central clinozoisite-sphene part of the propylitic zone, and contain minor scheelite and rare wolframite, cassiterite, molybdenite and chalcopyrite.
     石英-电气石脉及与其有关的云英岩边(花岗岩中的石英-白云母-金红石,变质沉积岩中的石英-白云母-电气石)仅见于绿磐岩的中央斜黝帘石-榍石部分,并且明显地晚于后者生成。 它们含有少量的白钨矿和很少的黑钨矿、锡石、辉钼矿和黄铜矿。

  quartz-tourmaline
On the textures and paragenesis of the gold-quartz-tourmaline veins of Ondonoc, W.-Ethiopia
      
The gold-quartz-tourmaline veins of Ondonoc occur in diorites and schists and follow the non-distortion planes of the theoretical strain ellipsoid.
      
Precambrian and Early Palaeozoic submarine exhalative Sn and W deposits are most commonly present in thick deep water sequences comprising pelites, carbonate, calcsilicate and cherty rocks, mafic volcanics and quartz-tourmaline rocks.
      
It occurs as a conformable banded quartz-tourmaline lithological unit comprising at least 15% and as much as 50% of the rock.
      
We have analyzed the chemical composition and boron isotope composition of tourmaline from tourmalinites, granite and a quartz-tourmaline vein from the Deri ore zone and from a pegmatitic band in the Rampura-Agucha ore body.

The action of metallic ions(Pb~(2+),Cu~(2+),Fe~(2+))on the main gangue

本文研究了金属离子(Pb~(2+)、Cu~(2+)、Fe~(2+)对与黑钨矿共生的主要脉石矿物——石英电气石、方解石作用情况。结果表明:用甲苯肿酸为捕收剂时,这些离子对电气石、方解石浮选无明显影响,而Pb~(2+)、Cu~(2+)离子对石英有明显活化作用。金属离子对矿物的作用受矿物组成、结构特征、金属活化离子的种类、水解特性及所采用的捕收剂的影响。

In the paper,the effect of lead nitrate,sodium humate and sodium silli- cate on surface electrical properties and floatability for wolframite and main- ly associated gangues-quartz,elbaite and calcite was studied.And the flotation separating experiment of synthetic mixed minerals,such as wolfra- mite-quartz,wolframite-elbaite and wolframite-calcite,was carried out, too.It was shown that besides pH value and depressant,the type and amount of gangue mineral was also an important and effective factor for flotation...

In the paper,the effect of lead nitrate,sodium humate and sodium silli- cate on surface electrical properties and floatability for wolframite and main- ly associated gangues-quartz,elbaite and calcite was studied.And the flotation separating experiment of synthetic mixed minerals,such as wolfra- mite-quartz,wolframite-elbaite and wolframite-calcite,was carried out, too.It was shown that besides pH value and depressant,the type and amount of gangue mineral was also an important and effective factor for flotation separation process on condition that O.P.toluene arsonic acid was used as a collector and lead nitrate was used as an activator.

本文研究了铅盐、水玻璃、腐植酸钠对黑钨矿及其主要伴生脉石矿物——石英电气石,方解石的表面电性质及可浮性。并对黑钨矿与上述伴生矿物组成的人工混合矿进行分离浮选试验。结果表明:在以甲苯胂酸作捕收剂、硝酸铅为活化剂的条件下,分离浮选除应正确选择介质 pH 值和抑制剂外,伴生脉石矿物的种类和含量是重要的影响因素。

The 'S' type Barrytown biotite granite pluton which intrudes Lower Ordovician greywacke and shales is exposed noar its original roof level. The pluton is internally zoned from a biotite-rich margin to an acid core. Mild pervasive hydrothermal alteration which affects much of the pluton comprises 3 distinct varieties: early propylitic alteration(chlorite-sericite±clinozoisite, sphene) was concentrated above the NW-SE trending, residually warm pluton core, while later intermediate argillic alteration (kaolinite,...

The 'S' type Barrytown biotite granite pluton which intrudes Lower Ordovician greywacke and shales is exposed noar its original roof level. The pluton is internally zoned from a biotite-rich margin to an acid core. Mild pervasive hydrothermal alteration which affects much of the pluton comprises 3 distinct varieties: early propylitic alteration(chlorite-sericite±clinozoisite, sphene) was concentrated above the NW-SE trending, residually warm pluton core, while later intermediate argillic alteration (kaolinite, illite-tourmaline) developed in the vicinity of roof contacts due to trapping and condensation of acid volatiles. Quartz-tourmaline veins and associated greisen selvedges (quartz-muscovite-rutile in granite, quartzmuscovite-tourmaline in metasediments) are restricted to, and apparently pcstdate, the central clinozoisite-sphene part of the propylitic zone, and contain minor scheelite and rare wolframite, cassiterite, molybdenite and chalcopyrite. Abundant secondary Ti-phases may have held magmatic Sn, W in situ during alteration of biotite, preventing effective leaching and potential ore concentration.

侵入奥陶纪下部硬砂岩和页岩的‘S’型巴里汤黑云母花岗岩体在接近其原始顶板位置出露地表。该岩体从富黑云母的边缘至酸性的核部呈内部分带现象。影响很大一部分岩体的弱弥漫型热液蚀变由三种有明显区别的类型组成:早期绿磐岩化(绿泥石-绢云母±斜黝帘石、榍石)集中于北西-南东走向的、当时尚有余温的岩体核部上方,而其后的中性泥质蚀变(高岭石、伊利石-电气石)发育于顶板接触带附近,这是由于捕获和凝聚酸性挥发分造成的。石英-电气石脉及与其有关的云英岩边(花岗岩中的石英-白云母-金红石,变质沉积岩中的石英-白云母-电气石)仅见于绿磐岩的中央斜黝帘石-榍石部分,并且明显地晚于后者生成。它们含有少量的白钨矿和很少的黑钨矿、锡石、辉钼矿和黄铜矿。在黑云母蚀变过程中,丰富的钛相矿物可能在原地捕获岩浆的锡和钨,这阻碍了有效的淋滤和矿石的富集。
