However,very low Mn contents(average 19.8ppm),relatively high Sr contents(average 137ppm)and the homogenization temperatures measured in fluid inclusions of crystalline dolomite do not support the hypothesis that meteoric water as high as 94% involved the dolomitization.
但极低的锰含量、相对较高的锶含量和包裹体均一化温度等资料均不支持有94%的大气淡水参与了结晶白云岩的白云石化作用,其白云石化流体应是埋藏成岩过程中囚禁的近同期、但是非同期的海源流体,其来源可能与埋藏成岩过程中该时间段蒸发盐的溶解有关。

结果表明:显生宙以来海水组分发生变化,经海相非骨骼灰岩和钾盐蒸发岩矿物学研究,发现这两种沉积岩长期以来连续变化,在"文石海"是MgSO4型蒸发盐,在"方解石海"是KCl型蒸发盐,从白垩纪晚期、第三纪早期的底部石盐溴含量及矿物学特征表明,此时处于"方解石海",古海水组分的特点是造成缺硫酸盐型钾盐矿床形成的物化基础;通过NaCl-KCl-MgCl2-H2O和NaCl-KCl-MgCl2-CaCl2-H2O两个体系相图的分析认为,当时所形成的成钾原始体系母液是高镁、低钾氯化物型的卤水,在母液蒸发过程中,由于原始海侵母液与残余高镁母液的掺杂作用,致使结晶路线直接从氯化钠区到E点母液或光卤石与氯化钠共饱线上,而没有通过氯化钠和氯化钾的共饱线,因而在矿体中氯化钾相很少或几乎不存在,由于外界CaCl2型水体的掺杂,使成钾母液进入光卤石相区,随着蒸发的进行,最终形成溢晶石矿物。

Therefore, the western Taim basin has been considered to be a favorable location in search for ancient sylvinite deposits. In order to indentify its marine or continental sedimentary facies and also the sedimentary stages, the authors selected the late stage evaporates of gypsum and salt minerals and measured the values of sulfur and chlorine isotopes.

The experimental results show that: lithium is scatteredly precipitated as natural lithium carbonate in the whole evaporation process, and the highest content of natural lithium carbonate in solid phase is 2.0%, so it is difficult to get the mixed salt with high-grade lithium carbonate; boron is precipitated as borax in the whole evaporation process, and borax is precipitated in large quantity with the highest content of 15.64% in solid phase until the brine is extremely concentrated (CWR≥97.9%) and intergrows closely with typical cold-phase natron; potassium is precipitated as sylvite and aphthitalite in the whole evaporation process with a content from 9.49% to 34.44%.
结果表明:在低温蒸发状态下,锂以天然碳酸锂形式在整个蒸发过程中分散沉淀,固相最高含量仅达2.0%,因此难以获得较高品位的富锂混盐;硼在全蒸发过程中以硼砂形式自然沉淀。当卤水高度浓缩(蒸失率达97.9%以上)时大量析出并与典型冷相矿物泡碱紧密共生,固相中硼砂含量最高可达15.64%;钾以氯化钾和钾芒硝形式沉淀,在蒸发浓缩的全过程中均有不同程度析出,固相含量在9.49%~34.44%之间波动。

Sulfur isotope of franeolite indicate that sulfur isotope value of phos phate concretion is larger than that of evaporite sulfate, there is little doubt that sulfur isotope fraetionation happens during phosphorite diagenesis, heav ier sulfur is laid in sediments because of formation of H〓S.
磷结核的稳定S同位素测试表明:其值大于同时代海水蒸发盐的值,这是由于在成岩作用过程中发生了S同位素分馏,生成H〓S,从而使沉积物中富集〓S。

This class of deposits is characterized by the abundance of iron oxide in the ores and the associated intensive regional sodic alteration. They may occur in Proterozoic intracraton or Phanerozoic continental margin volcanic arcs with nearby intrusive complex or evaporite. The spatially and temporally associated intrusive rocks are magnetite-series granitoids. Mineralization mainly occurs in second order echelon structures near the main regional structure.
该类矿床以矿石中含有大量的铁氧化物且伴有很强的区域性钠质蚀变为特征,可以产于元古代克拉通内或新生代大陆边缘岛弧环境,其周围具火成岩或含蒸发盐层,时空上与之有关的侵入岩为磁铁矿系列花岗岩,矿化主要产于近区域主断裂的羽状次级断裂中。

There is argument whether the fluids responsible for mineralization is a dominant magmatic source or controlled by host rocks. The main genetic models include "an evaporite source model","a fluid heating model" and "a magmatic-hydrothermal model".
对成矿流体是主要来自岩浆还是受围岩控制尚有争论,成矿模式有蒸发盐来源模式、外来流体加热模式和岩浆-热液流体模式。
