PostPosted: May 20, 2018 01:56    Post subject: Sedimentary, Iron, Minerals. Curious.  

Hi,
I have been excavating iron ore (may be siderite) for 6 months. My Fe contents range from 30% to Fe 58%. Currently i am supplying it to the cement factory. I want to share some of the images with you as i come across many new minerals daily and i just don't know them. Here we don't have much resources, Labs are very expensive. My purpose of sharing it with you is to acquire some knowledge as i have lot of interest in mining.
Here my Mining Place is Sedimentary Formation and we have to mine vertical. we have very best form of Gypsum here and we have wide seams of it. Then we have Silica Sand just after the Iron ore Seam following with shale seam. I want to dig into the following questions.

1. What form of Iron you think it is? Siderite??
2. What is the dark green mineral?
3. What are the pellets kind of thing in this rock?
4.What do you think of this formation?

This is the dark green thing. These can be found in my iron ore querry. I want to know its name?
Regards.

Hi Khosa,

1. Judging by the high iron content of your ore, the appearance of the first photograph, and your description and photograph of your quarry, I would suggest the following about the ore:

The colour (reddish-purple) and iron content suggest that the basic ore mineral is haematite (iron oxide, Fe2O3).
The haematite appears to be the matrix of a sedimentary conglomerate body, deposited in a succession of shales, sandstones and gypsum. THis type of geology certainly occurs in the Sulaiman Range west of DGK

2 and 3. Your next questions follow on from the observation that the ore is a conglomerate. The "pellets" are the clasts in the conglomerate (a conglomerate being a sedimentary rock made up a coarse fragments of other rocks).
The "green mineral", which clearly occurs as clasts in the conglomerate (lower right of picture 1) looks to be fragments of an igneous rock, either basalt or dolerite.

4. Without knowing where your quarry is located, it isn't possible to say much about the formation (age, depositional envirowww.gsp.gov.pknment etc).
If you want to find out more, the Geological Survey of Pakistan (www(dot)gsp(dot)gov(dot)pk is a great resource for maps and field reports. The Government of the Punjab Mines and Minerals department (http(colon slash slash)www(dot)mnm(dot)punjab(dot)gov(dot)pk is probably also a good resource for local information.

Good luck with the quarry!

Kevin

Thanks Kevin.
You are on the spot. This is actually koh Sulman range and west side. We have recently discovered coal too. If our iron is hematite then we should supply it to steel mills rather then cement company. Thanks again.

There is a free pdf at this address:
http://sujo.usindh.edu.pk/index.php/SURJ/article/viewFile/1288/1189
(link normalized by FMF)
Title: Updated Stratigraphy and Mineral Potential of Sulaiman Basin, Pakistan. Might give some ideas and references. It is only 28 pages, but seems to have some text that might be relevant.
