The barometry is an important part of studies of magmatic inclusions. Based on authorl's study results, this paper presents and reviews divers barometry methods on magmatic inclusions. There are two barometry methods of magmatic inclusions: direct and indirect. 1.Direct methods Natural basic magmas are often saturated or supersaturated by CO_2. The minerals of basic magmatic rocks and of lherzolite nodules in the alkaline basalts contain fre- quently the primary CO_2 inclusions associated with magmatic inclusions...

The barometry is an important part of studies of magmatic inclusions. Based on authorl's study results, this paper presents and reviews divers barometry methods on magmatic inclusions. There are two barometry methods of magmatic inclusions: direct and indirect. 1.Direct methods Natural basic magmas are often saturated or supersaturated by CO_2. The minerals of basic magmatic rocks and of lherzolite nodules in the alkaline basalts contain fre- quently the primary CO_2 inclusions associated with magmatic inclusions and the primary CO_2-bearing magmatic inclusions. These two sorts of inclusions can be used directly for barometry studies of magmatic inclusions. Natural intermediate-acid magmas contain a lot of dissolved volatie components (mainly H_2O). The magmatic inclusions and the aqueous inclusions coexisting in the minerals of this type of intermediate-acid igneous rocks can be also used directly for barometry studies of magmatic inclusions. 2.Indirect methods In the case of the absence of CO_2-bearing magmatic inclusions or coexisting ma- gmatic inclusions and fluid inclusions(CO_2 inclusions and aqueous inclsuions), we can plot the values of homogenization temperature of magmatic inclusions and their chemical comp osition into some experimental facies diagrams of silicate system, and evaluate the pressures at trapping of magmatic inclusions. Besides this, we can utilise some geothermobarometer for evaluating the pressures at trapping of magmatic inc- lusions in terms of the data of thermometry and chemical composition of magmatic inclusio ns.

测压是岩浆包裹体研究的一个重要方面。本文根据作者的研究结果,介绍和评述岩浆包裹体的各种测压方法,并重点介绍岩浆包裹体测压的直接法和间接法。 1.直接法:天然基性岩浆常饱和或过饱和CO_2。基性岩浆岩和碱性玄武岩二辉橄榄岩包体的矿物常含有与岩浆包裹体共生的原生CO_2包裹体以及原生含CO_2岩浆包裹体。这两种包裹体均能直接用于岩浆包裹体测压研究。天然中-酸性岩浆含大量溶解的挥发组分(主要是H_2O)。这类中-酸性火成岩矿物中共存的岩浆包裹体和含水包裹体也可直接用于岩浆包裹体测压研究。 2.间接法:在缺乏含CO_2岩浆包裹体或共存的岩浆包裹体和流体包裹体(CO_2包裹体和含水包裹体)时,可将岩浆包裹体的均一温度值及其化学成分投于某些硅酸盐系统实验相图之中,估算岩浆包裹体捕获时的压力。也可根据岩浆包裹体的测温和化学成分数据,利用某些地质温度压力计来估算岩浆包裹体捕获时的压力。

This note presented a new practical algorithm for carrying out functional abstraction with respect to object templates (an object template may be a data structure with variables as its atomic elements) on combinatory obs. This algorithm can perform the abstraction with respect to all specified variables in a single step, yield abstracts (combinators) in a concise form, and retain most, if not all, of the natural parallelism of the original combinatory ob in a straightforward form.

本文提出一种新的实用的“合成项(combinatory obs)对于对象模板的函数抽象算法”,这种对象模板可以是含变量原子成分的数据结构,即结构对象模板。算法保持了[2]的“在一步中对于所有规定变量实施抽象”和“产生一个简明的抽象(合成子(combinator))”这些特点。而且,还以直接的形式保留了“原给合成项中(若非全部,至少)绝大部分的自然并行计算。

On the basis of the mechanism of formation of mineral inclusions, it may be assumed inat a certain relation exists between the compositions of fluid inclusions in various minerals formed at the same stage of hydrothermal activity. In order to study the genetic relationships in between different minerals in the Bayan Obo iron deposit, the compositions (K~+, Na~+, Ca~+, Mg~+, F~+, Cl~+, ∑CO_2, SO_4~(2_) and pH) of inclusions in fluorite (23), hematite (13), magnetite (3), sodium pyroxene (2) and dolomite (5) from...

On the basis of the mechanism of formation of mineral inclusions, it may be assumed inat a certain relation exists between the compositions of fluid inclusions in various minerals formed at the same stage of hydrothermal activity. In order to study the genetic relationships in between different minerals in the Bayan Obo iron deposit, the compositions (K~+, Na~+, Ca~+, Mg~+, F~+, Cl~+, ∑CO_2, SO_4~(2_) and pH) of inclusions in fluorite (23), hematite (13), magnetite (3), sodium pyroxene (2) and dolomite (5) from the main mine and the eastern mine were determined by using the vacuum decrepitation and leaching methods, and cluster analyses of the data on the compositions were made. The Q-mode cluster analysis indicates that some iron oxide minerals in the deposit are related to dolomite of sedimentary origin, while others are related to fluorite and sodium pyroxene-—roducts of hydrothermal activity. The R-mode cluster analysis shows that the components of the leaching solution may be divided into two groups: one includes ∑CO_2, Mg~(2+) and H~+ (pH), which are obviously associated with dolomite; the other comprises Na~+, K~+, Ca~+, F~+, Cl~- and SO_4~(2-), which may possibly represent the composition of hydrotherreal solutions.

用真空烧爆、水浸取法测定了白云鄂博铁矿主、东矿的萤石、赤铁矿、磁铁矿、钠辉石、白云石等矿物的包裹体成分(钾、钠、钙、镁、氟、氯、SO_4~(2-)、和ΣCO_2及pH)。成分数据的聚类分析表明,氧化铁矿物一部分与沉积成因的白云岩有关,而另一部分与热液交代产物(萤石、钠辉石)有关。300℃和5×10~7Pa时,酸性Na-F-Cl溶液在“静态-动态”交替条件下与赤铁矿-白云岩反应的结果是形成萤石-赤铁矿-钠(铁)硅酸盐组合。流动反应有利于交代作用的进行和铁在热液中运移。
