it was rather enlightened to know the difference of twinning law between plagioclase and k-spar. carlsbad twins usually seen in k-spar mineral while polysynthetic twins will be found on plagioclase. it became polysynthetic because the way it formed where it 'stacked' upon each other, layer by layer. hmmm, really amusing. haha! understand? :)
when i finished the lab, it was snowing heavily outside. luckily i wore the columbia jacket, but still i didn't bring my snow cap, where i end up to lose the sensation of my ear. it is weird, the local said, of the weather here nowadays. sometimes it warm and sometimes it cold. Minnesota used to be very cold during this time. global warming is the culprit, the said, or to be more specific, human activities that result in global warming. in geology, i've learned that earth's climate can change to such an extreme weather. the earth even once hypothesized has been in this ice ball stage, where everywhere was snowing on earth. and earth can also change to becoming even hotter. well, regardless of those theories, man still need to be responsible for what they have done to earth. Allah also stated in the al-Quran about damages on earth because of man's hand. just love our earth. huh? environmental activist? no la, just someone who care about the place he live in, and happens to care for the next generation too...
