Kinematic and tectonic implications of crenulation cleavage, kink bands, and mesoscopic folds in the Baraboo Syncline, Wisconsin (∼1.45 Ga Picuris Orogen)
No full textThe Baraboo Syncline of Wisconsin is a south-verging, regional-scale fold that formed during the ∼1.45 Ga Picuris Orogeny. It involves Mesoproterozoic quartzite and phyllite of the Baraboo Quartzite. Phyllite layers preserve two deformational assemblages. D1 includes the regional-scale flexural-slip to flexural-flow syncline and associated mesoscopic parasitic folds. It also includes spaced cleavage in quartzite layers and north-dipping phyllitic cleavage in phyllite layers. On the gently north-dipping south limb of the regional syncline, parasitic folds verge south (out-of-the-hinge). On this limb, D2 includes north-verging monoclinal kink bands as well as south-dipping asymmetric crenulation cleavage; kink bands have not been found on the north limb. Crenulation growth micro-folded phyllitic cleavage domains into asymmetric sigmoids that are shaped like an ‘S\u27 on the Baraboo Syncline\u27s south limb and like a ‘Z\u27 on the fold\u27s north limb (as viewed looking east). The origin of D2 structures has long been controversial. Some authors attribute them to a post-syncline phase of extensional tectonism on north-dipping shear zones, whereas others consider them to be a consequence of progressive crustal shortening that continued after D1 fabrics had developed. Our structural analysis supports the second hypothesis and therefore implies that the manifestation of the Picuris Orogeny in southern Wisconsin did not include a post-syncline extensional phase. This interpretation is compatible with a tectonic model in which the Baraboo Syncline formed during inversion of a rift or pull-apart basin during north-south crustal shortening. Specifically, we found no north-dipping normal-sense shear zones, and we demonstrate that the kink bands and asymmetric crenulation of the south limb accommodated a component of north-south shortening in the plane of phyllitic cleavage. Published analog models show that the north-verging kink bands of the south limb could have developed in the same deformation regime as did south-verging parasitic folds. The geometry of crenulation in the north limb indicates that it could be an extensional crenulation accommodating stretching of the limb once it was steep. Late-stage flattening at a high angle to bedding on the south limb locally rotated the crenulation cleavage domains to a sub-horizontal dip. Outcrops in the Baraboo Syncline emphasize that asymmetric crenulation is a fungible fabric, in that examples with similar appearance can accommodate different strains and displacements depending on local context

wear$: For the Data Driven Shopper
No full textEveryone owns clothing that they never wear, right? What if there was a tool that could deter people from impulsive shopping and track the value of their clothes over time? Now there is. wear can also track the cost per wear of clothing already owned by the user. That data can inform future purchases of items and aid users in the process of cleaning out their closets. Users will add the name, a photo, link, number of wears and the price of any item they purchase. Over time as the user wears an article of clothing, they can update the total number of wears of that product. The cost per wear of the clothing item is calculated by dividing the total cost of the item by the number of wears. A user can utilize their cost per wear to see which items in their closet they do not wear frequently and what types of products they typically get the most wear out of. This process can also be done with an article of clothing that has not been bought yet so that users can see how many times they would need to wear an item to get their money’s worth from the purchase. Using data generated through the wear$ website, consumers take back the power to make smart decisions and end the cycle of constant consumption
