  amphiboles
The amphiboles show broad compositional variability.
      
Amphiboles of the amphibolites do not contain Cr at all.
      
Another difference of amphiboles from the metasomatic rocks and amphibolites is the depletion of this mineral in the former rocks in Al and Fe, the absence of K, but high concentrations of MgO and 1.5-2.0 times higher.
      
Syntactic intergrowths of various amphiboles and chlorites have been detected in pegmatoid ultramafic rocks.
      
In the concentrate from the placer, carbonado is associated with green corundum, various ilmenite, zircon titanian amphiboles and pyroxenes, rutile, anatase, and fragments of subvolcanic biotite picrites.

  amphibole group
The amphibole in hornfelses near the contact is kataphorite of the Na-Ca amphibole group.
      
Nephrite is a variety of tremolite-actinolite of the amphibole group, with variable iron and magnesium contents.
      
These two minerals belong to the amphibole group and previous analytical work has suggested the existence of a miscibility gap between them involving the segregation of calcium.
      
The amphibole group of minerals is made up of a number of mineral series.
      


Monoclinic amphiboles are double-chain silicate minerals containing Fe~(2+), Mg Ca, Na, etc. Five analyses and twelve Mssbauer spectra were obtained of the samples of hornblende, actinolite and hastingsite from granodiorite and skarn in the Nanjing-Zhenjiang area and from hornblende gneiss in western Henan. The results are presented as follows:(1) The chemical formula of the amphibole-group minerals is: A_(0-1)B_2C_5 T_8O_(22) (OH,F,Cl)_2, in which A=(Na,K)_(0.5), B=Ca_2, C= (Mg,Fe~(2+), Fe~(3+), Al~(Ⅵ), Ti,Mn)_5,...

Monoclinic amphiboles are double-chain silicate minerals containing Fe~(2+), Mg Ca, Na, etc. Five analyses and twelve Mssbauer spectra were obtained of the samples of hornblende, actinolite and hastingsite from granodiorite and skarn in the Nanjing-Zhenjiang area and from hornblende gneiss in western Henan. The results are presented as follows:(1) The chemical formula of the amphibole-group minerals is: A_(0-1)B_2C_5 T_8O_(22) (OH,F,Cl)_2, in which A=(Na,K)_(0.5), B=Ca_2, C= (Mg,Fe~(2+), Fe~(3+), Al~(Ⅵ), Ti,Mn)_5, T=[Si,Al~(Ⅳ)(Ti,Fe)]_8. Since Ca+Na>1 2/3 and Na<2/3, they all belong to the Ca-amphibole sub-group. In case Na+K>0.60 and the minerals are rich in ferric iron they all belong to hastingsites. Actinolite is generally rich in iron but poor in aluminum, whereas hornblende is rich in aluminum but poor in iron.(2) Six sites are occupied by cations in the structure of amphibole.(3) The ratio of Fe~(3+)/Fe~(2+) is 0.04—0.25±in amphiboles. Fe~(2+) first occupies the M_1 and M_3 sites and then the M_2 site,while Fe~(3+) first occupies the M_2 site and then the M_1 and M_3 sites. In a few samples Fe~(3+) is found occupying the T site of tetrahedron.(4) In hornblende M_1/2×M_3 and M_1/(M_1+M_3) are<0.70 and<0.60, respectively, while in actinolite and hastingsite they are>1.00 and>0.60, respectively, indicating that the former cations are present in the disordered state, but the latter ones are of ordered distribution. In addition,there are significant differences in Q.S. values between actinolite and hornblende.The differences in Mssbauer parameters for the amphibole-group minerals provide reliable spectroscopic data for distinguishing and studying the characteristics of rocks and the genesis of igneous magma or the mechanism of metasomatism or metamorphism.

天然的角闪石广泛分布在各种地质体和岩石中,它形成在不同物理化学环境下,因此,其成分和结构相当复杂;不同的学者根据其端点组分和内部结构的不同,曾设想出许多角闪石的分类方案。但这些都不能包含和完全合理的解释该族矿物中离子间的类质同象广泛发育和极其复杂的特征。 本文是对产于不同岩石中某些单斜晶系角闪石族矿物的穆斯堡尔效应的研究。一方面研究阳离子的占位和有序一无序特征,另一方面,这些闪石的上述特征在穆斯堡尔谱上的反映又可为它们的成因提供信息。

There aretwo kinds of core, the black and transparent,thl number of the later one were twiceor more than black core in 59% casesThere is significant difference of ferruginousbodies in pneumoconiosis and no pneumocon-iosis. Experts of abroad thought that 100asbestos bodies/g wet lung be limited value toseparate exposed and unexposed occupationalgroup. There are 1 to 150 times greater than100 bodies/g wet lung in 5O% cases. We foundthat there are the X-ray diffraction peaks ofd=8.434 and d=8.261. The dust is classifiedto amphibole. It may be one of factors offerruginous bodies' core formation.

本文用Smith消化法提取肺内粉尘及含铁小体,并对粉尘进行X线衍射物相分析。结果发现含铁小体的检出率为100%,含铁小体数量为1~15000个/克肺湿重,含铁小体等于和大于100个/克肺湿重的占59.04%,含铁小体透明轴心多于黑色轴心,59%的病例透明轴心的含铁小体为黑色轴心的两倍以上。而含铁小体的量又与有、无尘肺病有明显差异。国外研究将100个/克肺湿重做为职业性接触与非职业性接触石棉的界限。本研究50%的病例含铁小体高出100个的1~150倍,是值得认真探讨的。通过对肺内提取之粉尘做X线衍射物相分析发现,粉尘内有d=8.434,d=8.261的X线衍射峰,通过X线衍射矿物鉴定,属角闪石族石棉。它可能是形成含铁小体轴心的因素之一。
