DeLeón, Pepe's y Joe's, Kahlúa, Tepaches, Margaritas or some of 'Doug's Homebrew' ?    ;-)

Hi guys
 
 I think this is true, but really don't know if there is some more 
 subtile catch like some completely arbitrary distance someone measured 
 somewhere:
 
 In the conditons of formation, even though Sikhote is classified as an 
 octahedrite, most of the small specimens do not exhibit patterns and 
 are just small chunks of a single kamacite crystals, right?  So 
 whatever the main mass is called, really doesn't matter - these smaller 
 ones are chemically hexahedrites.  Because all a hexahedrite is  - is a 
 fragment of a kamacite crystal.
 
 In fact, some "hexahedrites" between 5-6% nickel are probably 
 "octahedrites" even by the TKW accounting method, only, the interface 
 wasn't discovered during classification.  Similar to the siderite vs. 
 pallasite discoveries of late.
 
 (In the case of the larger specimen that was labeled, probably it is 
 larfe enough to contain a crystal interface, so best to call it as 
 mentioned coarsest octahedrite.)
 
 kindest wishes
