35.8 grams. 45 x 45 x 6 mm. Thin section between crossed polarizers. H5
TKW 4 tons. Observed fall 8 March 1976, northern part of the district of Kirin, Kirin Province, China.
Bernd writes:
The slice harbors three solid FeNi puddles and some shock veins traversing the slice.
The thin section photo was taken in cross-polarized light. Magnification is 16x. The chondrule at center is a BO chondrule, a barred olivine chondrule, with a thin inner rim in optical continuity and a thick igneous rim around it. The olivine bars are set in black glass. The neighboring chondrule is a polysomatic BO chondrule
showing several sets of parallel bars. |

Thank you Bernd for another great educational submission!
On the alteration of "chondrules and chondroids", Merrill (1920) referenced Merrick (ca. 1761) when he wrote, explaining the different perceptions of metamorphism of chondrules:
"My children,* the Chameleon cries*
(Then first the creature found a tongue),*
*You all are right, and all are wrong.* 70
When next you talk of what you view,*
Think others see as well as you;*
Nor wonder if you find that none*
Prefers your eyesight to his own.* |
