h2743 Sample# A1 IR14
0.5g -420+200u"
Iran - Fatemeh
Sepidbar
"Coarse brown garnet, brecciated, with minor carbonate"
h2744 Sample# B4 IR14
0.5g -420+200u"
Iran - Fatemeh
Sepidbar
"massive black magnetite, minor carbonate, weakly magnetic only"
h2745 Sample# C4 IR14
0.5g -420+200u"
Iran - Fatemeh
Sepidbar
"massive black magnetite, minor sulphide, moderately magnetic"
h2746 Sample# 2-13 IR14 1.0g
-420+200u"
Iran - Fatemeh Sepidbar
"brown-black vuggy haematite, non-magnetic. From volcanics."
h2747 Sample# 2-14 IR14 0.5g
-420+200u" ?Baryte hand separation
Iran - Fatemeh
Sepidbar
"coarse ?baryte and haematite, non-mag. does not react with 10%
HCl, suspected baryte"
h2748 Sample# 2-14
IR14 0.5g -420+200u haematite
dominant hand separation Acid washed
repeat of run H2747
Iran - Fatemeh
Sepidbar
"coarse ?baryte and haematite, non-mag. Acid washed, but
unreactive, suspected baryte"
h2749 Sample#
3-6 IR14
1.0g -420+200u haematite
Iran - Fatemeh
Sepidbar
"brown-black vuggy haematite, non magnetic. From volcanics"
h2744 IR14 B4 95% mag/haem grains.
magnetic separated. But only weakly magnetic, so dominantly
haematite.
Other minerals are mostly CO3 (has crystal faces) in
composite grains.
traces of white non-crystalline material.
no sulphide Feox has speckled surfaces, not micaceous
h2745 IR14 C4 90% mag/haem
grains. magnetic separated
Micaceous haematite with curved surfaces.
Very rare traces of sulphide. (hand specimen had more, but
probably not magnetic)
most non-Feox are white, non-crystalline. Trace CO3. no qtz?
h2743 IR14 A1 garnet mag
separated
semi translucent light brown 95% garnet, trace quartz, minor
magnetite / haematite No sulphide
saw 1 nice octahedral Magnetite crystal
