twinning occur cause of growth of two crystal in same plane, in twinning we have just one substance, but ex-solution occur cause of cooling and here we have two substance. m.piroui@gmail.com

Color is lead to silver gray sometimes with a bluish tint.Luster is metallic to dull in weathered faces.Transparency crystals are opaque.Crystal System is isometric; 4/m bar 3 2/mCrystal Habits include the cube, octahedron and combinations of the two. Spinel twinning is possible forming flattened crystals. Also massive and granular.Cleavage is perfect in four direction forming cubes.Fracture is uneven and rarely seen because of the perfect cleavage.Hardness is 2.5+Specific Gravity is approximately 7.5+ (heavy even for metallic minerals)Streak is lead grayAssociated Minerals are calcite, dolomite, sphalerite, pyrite and other sulfide minerals, also lead oxidation minerals such as cerussite and anglesite.Other Characteristics: brighter metallic luster on cleavage surfaces than on crystal faces.Notable Occurances include Texas-Oklahoma-Missouri area, USA; Germany, Peru, Mexico, Zambia, and England.Best Field Indicators are crystal habit, cleavage and, perhaps most importantly, density.
There are many. Which is most dangerous depends on how you measure it. Alberta has the #63. A two lane road supplying Canada's oil industry. Most of Canada would be shocked at the volume of traffic and the condition of the road combined with the wealth that travels it. Deaths average about a dozen a year over the last few years for a town of less than 100,000. Part of the problem is the mix of drivers. Many are so intimidated they will not pull over for three wide passes and many head on's result. A recent one killing 7 in one crash. Another part of the reason is funding. Western Canada has to build it's own roads, rarely getting the 1/3rd funding common elsewhere. The attitude that Western Canada should pay into Confederation but not get the same services other regions do will become obvious with this list. It is why the #1 and #16 TransCanada Highways are also dangerous. Though they are TransCanada highways and this is the 21st century they have yet to be twinned. The section on the #1 around Golden has been upgraded with some twinning and more passing sections it still has old sections and they are dangerous. The #1 around Rogers Pass is well known to be very dangerous. This section has many truck crashes and is all to often closed to any traffic. As is the section around Banff. It isn't just Alberta and BC with problem roads. Saskatchewan's highway #11 is very risky. Several people a year are killed there. The TransCanada #1 in Manitoba is often closed due to serious crashes and weather. It is twinned but little money has been spent on addressing the wind and snow. Next time you drive through there look at the snow fence being used, yep that 6' portable orange plastic fence is all they can afford. Manitoba has a highway 11 which is easily the most dangerous by many measures. The section to Traverse Bay I have personally avoided. And for good reason. It has managed to kill a person for every 10kms of road in 2009, other years also show the result of poor design and funding. The roads in the territories are so bad it has resulted in a TV series called Ice Road Truckers. The show has some hype but those roads really are that dangerous. There is no doubt the worst roads in Canada are in the West and North and as I mentioned Canadian funding practices are clearly a major part of the problem but Eastern Canada has some poor roads as well. Most notably would be roads around Toronto, 401 in particular, and highway 103 in Nova Scotia.
Job twinning is when a co-operative education student is observed at his or her placement For either a half or full day.

Twinning is formation of twin crystals like Siamese twins during crystallization which follow defined twin laws e.g. Spinel and Albite.
Twining plants are climbers.
The cow.
Artificial embryo twinning is a low tech form of cloning.The technology mimics the natural process of creating identical twins.
Jersey Shore - 2009 Twinning 4-3 was released on: USA: 18 August 2011
Plagioclase.
1-Slip occurs in distinct atomic spacing multiples, whereas the atomic displacement for twinning is less than the inter-atomic separation, usually proportional to their distancesfrom the twin plane. 2-for slip, the crystallographic orientation above and below the slip plane is the same both before and after the deformation; for twinning, there will be a reorientation across the twin plane.
Not usually, only the heifers are affected by infertility due to twinning.
There are several, including isometric forms such as cubes and octahedrons, twinning is also seen.
The difference of the vines from a herbs are they are climbing and twinning plants while the herbs have soft and succulent stem.....thanks!
