After a while of investigating on the internet, I have found no understandable explanation.Some say it is hydrothermal when some dont even mention it.Please guys.it may mean my whole grade!
You should stop worrying about flats and learn how to repair one if it happens. If you know how, it is a 10 minute job to repair a flat and be back on your way. A $10 tire is a cheap tire by any standard, tubes make very little difference to flat resistance. There are tires with various types of puncture resistant layers available, but they cost a lot more than $10.
buy better tubes and tires those are cheap! i've had new tubes that couldn't hold air more than 24hr but i've also had tubes that have held for years. if there's anything left in tire from previous flat that will puncture tube? are you installing correctly? specialized makes tires with a kevlar belt in them. check stem make sure nipple inside is tight. you should be checking tire pressure before every ride too.
Deep sea sedimentation produces limestone/dolomite. Hydrothermal vent activity/reactions in these sediments results in lead/zinc deposits. The exact mechanisms are actually still under dispute, believe it or not.
