Knowing the age of the rocks that contain the metals and minerals we explore and mine might sound like an esoteric pursuit for academic geologists. Why should a savvy investor care how old the rocks are? Does it really matter if the gold is hosted in rocks that are 2 billion or 3 billion years old? Understanding the ages of the rocks that host economic mineralization is critical to finding more mineralization, from the property scale to a global scale, and it can be a guide to how prospective a patch of ground really is. You might remember from previous explainer articles that economic mineral deposits often form when magma molten, or partially melted, rock beneath the Earth’s surface is pushed up and into other rocks nearer the surface. The magma brings heat and metal-rich fluids that perforate through rocks and into faults and fractures, which then cool and trap metals to form mineral deposits. One example is the Archean, the period 4 to 2. Some of the richest mineral deposits in the world are found in similar rocks of the same age! It is not a coincidence.

First, there was love and heartbreak. Most of these are not only perplexing but also symptomatic of our decreasing ability to communicate with each other without the use of technology in a healthy manner. Stringing someone along without any commitment or clarity about where their interaction is headed, by sending in the occasional message, mentioning in passing they want to meet, but never making an actual plan.
This extends from outright cheating in a relationship to flirting with multiple people at the beginning of a relationship, should the worst happen. The mother of all modern dating trends, ghosting is exactly what it sounds like: a romantic interest simply disappearing without warning or closure after a few dates that were clearly heading towards commitment, almost as if they … died. A related term is ghostbusting when the ghostee forces the ghoster to reply and explain their behavior like a well-adjusted adult would do.
A considerably worse version of ghosting — curving is known as rejecting someone with a smile. Resurfacing back into a relationship or fling after ghosting someone, without so much as a casual mention of their disappearance in the first place — as if nothing happened — is known as submarining.

M oira Weigel , the author of Labor of Love: The Invention of Dating , argues that dating as we know it—single people going out together to restaurants, bars, movies, and other commercial or semicommercial spaces—came about in the late 19th century. What dating does is it takes that process out of the home, out of supervised and mostly noncommercial spaces, to movie theaters and dance halls. The application of the supply-and-demand concept, Weigel said, may have come into the picture in the late 19th century, when American cities were exploding in population.
Read: The rise of dating-app fatigue. Actual romantic chemistry is volatile and hard to predict; it can crackle between two people with nothing in common and fail to materialize in what looks on paper like a perfect match. The fact that human-to-human matches are less predictable than consumer-to-good matches is just one problem with the market metaphor; another is that dating is not a one-time transaction.
